A 10.0 cm3 sample of copper has a mass of 89.6 g. What is the density of copper

natali 33 [55]

Answer:

<h2>Density = 8.96 g/cm³</h2>

Explanation:

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

$Density = \frac{mass}{volume}$

From the question

mass of copper = 89.6 g

volume = 10 cm³

Substitute the values into the above formula and solve

That's

$Density = \frac{89.6}{10}$

We have the final answer as

<h3>Density = 8.96 g/cm³</h3>
