Question

A small cube of aluminum measures 15.6 mm on each side and weighs 4.20 g. What is the density of aluminum in g/cm³? a) 0.120 g/cm³ b) 1.42 g/cm³ c) 2.69 g/cm³ d) 8.75 g/cm³

Answer 1

It would be C. Here is why:

You notice there is a g/cm3 right? So we need to do 4.20 divided by 15.6.

You would end up with an answer of 2.69 g/cm3.

Hope this helps!
