Glycerol is a syrupy liquid often used in cosmetics and soaps. A 2.50-L sample of pure glycerol has a mass of 3.15 x 10^3 g. What is the density of glycerol in grams per cubic centimeter?

$\text{Density, } \rho$ $\cong$ $1.3 \cdot g \cdot c {m}^{-} 3$.
$\text{Density, } \rho$ $\equiv$ $\text{Unit mass"/"Unit Volume}$
Here, both mass and volume were quoted, and we simply take the quotient, knowing that $1 \cdot L$ $=$ $1000 \cdot c {m}^{3}$.
Thus "rho $\equiv$ $\frac{3.15 \times {10}^{3} g}{2.50 \cdot \cancel{L} \times {10}^{3} \cdot c {m}^{3} \cdot \cancel{{L}^{-} 1}}$ $=$ ??g*cm^-3
