What is the mass of an object that has a density of 8 g/mL and a volume of 64 mL?

The answer is 512 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume of object = 64 mL

density = 8 g/mL

The mass is

mass = 8 × 64

We have the final answer as

512 g
