Question

Object A has a mass of 12 g and a volume of 8 cm^3. Object B has a mass of 20 g and a volume of 8 cm^3. Which object has a greater density and by how much?

Object A, by 1 gram per cubic centimeter
Object A, by 8 grams per cubic centimeter
Object B, by 1 gram per cubic centimeter
Object B, by 8 grams per cubic centimeter

Answer 1

Density is mass divided by volume.

Object A: 12/8 = 1.5 g/cm^3

Object  B: 20/8 = 2.5 g/cm^3

2.5 - 1.5 = 1

Object B is greater by 1 g/cm^3
