# A student measures the mass of an 8 cm^3 block of brown sugar to be 12.9 g. What is the density of the brown sugar?

$\rho = \text{mass"/"volume}$, here $\rho \cong 1.6 \cdot g \cdot c {m}^{-} 3$

#### Explanation:

$\text{Density}$, $\rho$, is mass per unit volume and is thus defined as the quotient, $\text{mass"/"volume}$, and typically chemists use units of $g \cdot c {m}^{-} 3$ or $g \cdot m {L}^{-} 1$.

And here this quotient is...........

$\frac{12.9 \cdot g}{8 \cdot c {m}^{3}}$; does this give the required units?

Note that $1 \cdot c {m}^{3} \equiv 1 \cdot m L \ldots \ldots$
