What is the formula for calculating density?
What is the formula for calculating density?
- Density = Mass x Volume
- Density = Volume / Mass
- Density = Mass / Volume (correct)
- Density = Mass + Volume
If two objects have the same volume, but object A is heavier than object B, which object has a higher density?
If two objects have the same volume, but object A is heavier than object B, which object has a higher density?
- Object B
- It is impossible to determine without knowing the masses of the objects
- Object A (correct)
- Both objects have the same density
What is the relationship between the density of an object and the arrangement of its atoms?
What is the relationship between the density of an object and the arrangement of its atoms?
- The more tightly packed the atoms are, the lower the density
- The less tightly packed the atoms are, the higher the density
- The more tightly packed the atoms are, the higher the density (correct)
- Density is not affected by the arrangement of atoms
What are the units of measurement for density?
What are the units of measurement for density?
A student measured the mass of an object to be 10 grams and its volume to be 2 cm³. What is the density of the object?
A student measured the mass of an object to be 10 grams and its volume to be 2 cm³. What is the density of the object?
Flashcards
Density
Density
Density is the ratio of mass to volume, calculated as mass divided by volume.
Mass
Mass
Mass is the measure of the amount of matter in an object, measured in grams.
Volume
Volume
Volume is the amount of space occupied by an object, measured in cm³ or mL.

Study Notes
Density
- Density is calculated by multiplying mass and volume.
- Density is a measure of how tightly packed atoms are within an object. Higher density indicates more tightly packed atoms.
- Volume is measured in cubic centimeters (cm³).
- Mass is measured in grams (g).
- Density is often expressed as grams per cubic centimeter (g/cm³) but can also be expressed in grams per milliliter (g/mL).
