Question

9. What is the density of brass, a copper-zinc alloy, if a block displacing 40.8 cm3 weighs 324 grams?​

Answer 1

The answer is 7.94 g/cm³

Step-by-step explanation:

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

`density = (mass)/(volume) \\`

From the question

mass = 324 g

volume = 40.8 cm³

We have

`density = (324)/(40.8) \\ = 7.941176...`

We have the final answer as

7.94 g/cm³
