Question

A 10.0 cm3 sample of copper has a mass of 90 g. What is the density of copper?

Answer 1

9 g/cm³

Step-by-step explanation:

The density of a substance can be found by using the formula

• 
  `density = (mass)/(volume) \\`

From the question we have

`density = (90)/(10) = 9 \\`

We have the final answer as

9 g/cm³

Hope this helps you
