$\text{Density } \rho$ $=$ $\text{Mass"/"Volume}$

#### Explanation:

We has $\rho$, and we have $\text{mass}$.

And thus $\text{Volume}$ is the quotient $\frac{\text{Mass}}{\rho}$

$=$ $\frac{12 \cdot \cancel{g}}{4 \cdot \cancel{g} \cdot m {L}^{-} 1}$ $=$ ??*mL.

Note that the inclusion of units is an extra check on our calculations. We sought a volume; the answer we got had units of volume, i.e. $\frac{1}{{\left(m L\right)}^{-} 1} = \frac{1}{\frac{1}{m L}} = m L$.

This is a good indication that we are on the right track and have not made an error.
