Question

A cube of ruthenium metal `1.5` `cm` on a side has a mass of `42.0` `g`. What is the density in `g``/cm^3`?

Answer 1

`"Density"` `=` `"Mass"/"Volume"` `=` `??`

Explanation:

`rho,"density"` `=` `"Mass"/"Volume"` `=` `(42*g)/(1.50*cm)^3` `~=` `12*g*cm^-3`.

Clearly, the units are appropriate for density.
