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

Nov 26, 2016

$\text{Kilograms, cubic metres, and kg"*m^-3}$.

#### Explanation:

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

Because the ${m}^{3}$ is a very large volume $\left(1000 \cdot L\right)$, chemists typically use $g = {10}^{-} 3 k g$ to express mass, and ${\mathrm{dm}}^{3}$ (or $\text{litres}$) to express volume.

$1 \cdot {\mathrm{dm}}^{-} 3 = {\left(1 \times {10}^{-} 1 m\right)}^{3} = 1 \times {10}^{-} 3 \cdot {m}^{3} = 1 \cdot L$.

Chemists also typically use $g = {10}^{-} 3 k g$, to express mass.
