Question

What are the units for mass, volume, and density?

Answer 1

`"Kilograms, cubic metres, and kg"*m^-3"`.

Explanation:

And thus `rho("density")="mass"/"volume"`.

Because the `m^3` is a very large volume `(1000*L)`, chemists typically use `g=10^-3kg` to express mass, and `dm^3` (or `"litres"`) to express volume.

`1*dm^-3=(1xx10^-1m)^3=1xx10^-3*m^3=1*L`.

Chemists also typically use `g=10^-3kg`, to express mass.
