Apologia Chemistry 2nd Edition (c) 2009 Copyright Knowledge Box Central Exploring Creation With Chemistry 2nd Edition Lab Report Experiment #1.1 Air Has Mass Date: ______________ Name: _________________________ Supplies: * A meterstick (A yardstick will work as well; a 12-inch ruler is not long enough.) *Two 8-inch or larger balloons *Two pieces of string long enough to tie the balloons to the meterstick *T a p e * Safety goggles Procedure: 1. Without blowing them up, tie the balloons to the strings. Be sure to make the knots loose so that you can untie one of the balloons later in the experiment. 2. Tie the other end of each string to each end of the meterstick. Try to attach the strings as close to the ends of the meterstick as possible. 3. Once the strings have been tied to the meterstick, tape them down so that they cannot move. 4. Go into your bathroom and pull back the shower curtain so that a large portion of the curtain rod is bare. Balance the meterstick (with the balloons attached) on the bare part of the shower curtain rod. You should be able to balance it very well. If you don't have a shower curtain rod or you are having trouble using yours, you can use any surface that is adequate for delicate balancing. 5. Once you have the meterstick balanced, stand back and look at it. The meterstick balances right now because the total mass on one side of the meterstick equals the total mass on the other side of the meterstick. In order to knock it off balance, you would need to move the meterstick or add more mass to one side. You will do the latter. 6. Have someone else hold the meterstick so that it does not move. In order for this experiment to work properly, the meterstick must stay stationary. 7. While the meterstick is held stationary, remove one of the balloons from its string (do not untie the string from the meterstick), and blow up the balloon. 8. Tie the balloon closed so that the air does not escape, then reattach it to its string. 9. Have the person holding the meterstick let go. If the meterstick was not moved while you were blowing up the balloon, it will tilt toward the side with the inflated balloon as soon as the person lets it go. This is because you added air to the balloon. Since air has mass, it knocks the meterstick off balance. Thus, air does have mass! 10. Clean up your mess.

Fill your sink with water until the water level is high enough to submerge the entire glass. 2. Make sure the inside of the glass is dry. 3. Wad up the paper towel and shove it down into the bottom of the glass. 4. Turn the glass upside down and be sure that the paper towel does not fall out of the glass. 5. Submerge the glass upside down in the water, being careful not to tip the glass at any time. 6. Wait a few seconds and remove the glass, still being careful not to tilt it. 7. Pull the paper towel out of the glass. You will find that the paper towel is completely dry. Even though the glass was submerged in water, the paper towel never got wet. Why? When you tipped the glass upside down, there was air inside the glass. When you submerged it in the water, the air could not escape the glass. Thus, the glass was still full of air. Since air takes up space, there was no room for water to enter the glass, so the paper towel stayed dry. 8. Repeat the experiment, but this time be sure to tip the glass while it is underwater. You will see large bubbles rise to the surface of the water, and when you pull the glass out, you will find that it has water in it and that the paper towel is wet. This is because you allowed the air trapped inside the glass to escape when you tilted the glass. Once the air escaped, there was room for the water to come into the glass. 9. Clean up your mess.

Lay the book on a table and measure its length in inches. Read the ruler as I showed you in the measurement section above, estimating any answer that falls in between the markings on the scale. Once you do that, convert the fraction to a decimal (as we did in the measurement section above) and round it to the hundredths place, because that's the precision of an English ruler. 2. Measure the width of the book in the same way. 3. Now that you have the length and width measured, multiply them together to get the surface area of the book. Since you are multiplying inches by inches, your area unit should be in2. Remember to count the significant figures in each of the measurements and round your final answer so that it has the same number of significant figures as the measurement with the least number of significant figures. 4. Now take the length measurement and use the relationship given in Table 1.3 to convert it into cm. Do the same thing to the width measurement, making sure to keep the proper number of significant figures. Note that the relationship between inches and centimeters is exact, so the "2.54 cm" should not be taken into account when considering the significant figures, because 1 inch is exactly 2.54 cm. 5. Now use your metric ruler to measure the length and width of the book in centimeters. Once again, do it just like I showed you in the measurements section above. If the scale of the ruler is marked off in 0.1 cm, then your length and width measurements should be written to the hundredths of a centimeter. Compare these answers to the length and width you calculated by converting from inches. They should be nearly the same. If they are different by only a few percent, there is no problem. However, if they differ by more than a few percent, recheck your measurements and your conversions. 6. Finally, multiply the length and width measurements you took with the metric ruler to calculate the surface area of the book in cm2. Use the relationship between inches and centimeters to convert your answer into in2. Remember, since you are using a derived unit, the conversion is more complicated. You might want to review Example 1.4. 7. Now compare the converted value for the surface area to the one you calculated in step (3) using your English measurements. Once again, they should be equal or close to equal. If not, you have either measured wrongly or made a mistake in your conversion. 8. Clean up your mess.

A graduated cylinder would be ideal, but measuring cups will work as well. * A mass scale, preferably one that reads in grams. (The scale should not go much over 500 grams, or it will be very difficult for you to read the mass of the objects in this experiment.) Procedure: 1. First, measure the mass of the graduated cylinder, or whatever you have that measures the volume of a liquid. Be sure to write it down with the correct precision. If you are using a standard mass scale from a grocery store, its scale is probably marked off in units of 10 grams. Thus, you should be able to report the mass to a precision of 1 g. 2. Next, measure out 50.0 mL (1/4 cup if you are using measuring cups) of syrup. Now put the graduated cylinder (with the syrup in it) back on the scale and measure the total mass. Subtract the mass of the graduated cylinder from this number (using our rules for significant figures) to get the mass of the table syrup by itself. This method of measuring mass is called the difference method. Chemists often call it "measuring the mass by difference." 3. Now that you have the mass of the table syrup, and you know that its volume was 50.0 mL (because that's what you measured out), divide the mass by the volume to get the density. Be sure to follow our significant figure rules when you do this! Finally, pour the syrup into the tall glass. Repeat this procedure for both the water and the vegetable oil. 4. Once you have measured the density of all three substances, look at the tall glass. You should see that the table syrup is all at the bottom of the glass, the water forms a layer above that, and the vegetable oil is all in one layer on top! 5. Clean up your mess.
