Understanding Density Equations

What is the formula for density?

• Density equals volume divided by mass

• Density equals mass divided by volume

• Density equals mass times volume

• Density equals volume times mass

Which of the following best describes mass?

• The amount of matter in an object

• The amount of space an object occupies

• The density of an object

• The weight of an object

If an object has a mass of 13.7 grams and a volume of 6.0 cubic centimeters, what is its density?

• 2.28 grams per cubic centimeter

• 13.7 grams per cubic centimeter

• 2.28 cubic centimeters per gram

• 6.0 grams per cubic centimeter

How do you calculate the mass of an object if you know its density and volume?

• Divide volume by density

• Multiply density by volume

• Divide density by volume

• Subtract volume from density

A rock has a density of 3.5 grams per cubic centimeter and a mass of 2.5 grams. What is its volume?

• 2.5 cubic centimeters

• 1.4 cubic centimeters

• 0.7 cubic centimeters

• 3.5 cubic centimeters
