Well, we want to find the quotient......

#### Explanation:

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

And for chemists, the typical units are $g \cdot m {L}^{-} 1 \equiv g \cdot c {m}^{-} 3$.

And thus you take the mass of a known volume of liquid....and solve the quotient.

And some typical values, ${\rho}_{{H}_{2} O} = 1 \cdot g \cdot c {m}^{-} 3$; or ${\rho}_{H g} = 13.55 \cdot g \cdot c {m}^{-} 3$; ${\rho}_{B {r}_{2}} = 3.11 \cdot g \cdot c {m}^{-} 3$; ${\rho}_{\text{EtOH}} = 0.789 \cdot g \cdot c {m}^{-} 3$.

By the way, you won't be asked to find the density of bromine; there are few substances in the laboratory that are as dangerous or as corrosive as bromine.
