No of moles = given mass ÷ molecular mass
n = 55.98 ÷ (12+19×2+35.5×2)
Answer:
<h2>Density = 8.96 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of copper = 89.6 g
volume = 10 cm³
Substitute the values into the above formula and solve
That's

We have the final answer as
<h3>Density = 8.96 g/cm³</h3>
