If a sample has a mass of 1.25 * 10^2 g and a volume of 51 mL, what is its density?

$\rho \cong 2.5 \cdot g \cdot m {L}^{-} 1$
$\text{Density"="Mass"/"Volume}$
Here, $\text{Density } \rho = \frac{1.25 \times {10}^{2} \cdot g}{51 \cdot m L}$, which operation gives an answer in $g \cdot m {L}^{-} 1$, as is required for a density measurement.
