The density of brass is 8.89 g/cm^3. What is the density in kilograms per cubic meter?

Question

Hi im Having trouble with my homework for physics I was wondering if you will be able to help

Answer 1

This is simply a matter of converting g to kg and cm³ to m³.

8.89 g to kg = 0.00889 kg

1cm³ to m³ = 1x10^-6 m³

Thus, you now have 0.00889 kg/10^-6 m³

This is also equal to 8.89 kg/10^-3 m³

Since the question asks for density if kg/m³, just multiply by 1000 to get 8890 kg/m³
