What is the density of an object?

Question

An object with a mass of 10 g and a volume of 5 cm3 was placed into a container of water. 

Answer 1

Density is equal to mass divided by volume, so

 

D = m/V

D = 10g/5cm³

D = 2g/cm³

 

Water has a density of 1g/cm³, so the object is denser than water and will sink.
