Missing Values Mastery

How can you calculate the volume of a mineral using known values?

What is the volume of a mineral with a mass of 25 g and a density of 8.96 g/cm^3?

How can you calculate the distance of a race track using speed and time?

What is the distance of a race track if a racecar is going 125 mph and it takes 15 minutes to complete a lap?

How can you calculate the force exerted by a book on a table using pressure and area?

What is the force exerted by a book on a table if it exerts 2 pounds of pressure over 1 ft^2?

Determining a Missing Value

Determining unknown values from known ones is a valuable skill in science, commonly used in data collection and analysis.
You can calculate a missing value using simple mathematic relationships, as long as you know the other values.

Simple Algebra

To determine a missing value in an equation, you need to know the formula and have all the known values on the same side of the equation.
You may need to reorganize the formula to get the known values together.
Example: If you have the equation 2 + x = 5, you subtract 2 from each side to get x = 3.

Real-World Applications

If you know the density and mass of an object, you can calculate its volume using the formula: density = mass / volume.
Example: Copper chunk with density 8.96 g/cm^3 and mass 25 g, the volume is calculated to be 2.79 cm^3.
If you know the speed and time of an object, you can calculate its distance using the formula: distance = speed * time.
Example: Racecar with speed 125 mph and time 15 minutes, the distance is calculated to be 31.25 miles.
If you know the pressure and area of an object, you can calculate its force using the formula: force = pressure / area.
Example: Book with pressure 2 pounds/1 ft^2, the force is calculated to be 2 pounds/ft^2.

Test your skills in determining missing values with this quiz! Practice solving for unknown values based on known data, just like a scientist. Challenge yourself with questions on density, speed, and more. Put your analytical thinking to the test and see how well you can calculate missing values.
