Question

the metric units of density are: $\frac{cm^{2}}{g}$ nm $\frac{g}{cm}$ $\frac{g}{cm^{3}}$ $\frac{cm^{3}}{g}$

Explanation:

Density is defined as mass per unit volume. In the metric system, mass can be in grams (g) and volume in cubic - centimeters ($cm^{3}$). So the unit of density is grams per cubic - centimeter, $\frac{g}{cm^{3}}$.

Answer:

$\frac{g}{cm^{3}}$ (the fourth option in the image)
