PLEASE PLEASE HELP What is the mass of a sample material that has a volume of 72.2cm³ and a density of 7.7g/cm³?

The answer is

555.94g

Explanation:

To find the mass of a substance given it's density and volume we use the formula

Making mass the subject we have

mass = Density × volume

From the question

Density = 7.7 g/cm³

Volume = 72.2 cm³

Substitute the values into the above formula

That's

mass = 7.7 g/cm³ × 72.2 cm³

We have the final answer as

Hope this helps you
