Question

what is the correct equation to use to calculate density?
density = \frac{volume}{mass}
density = \frac{mass}{volume}
density = mass \times volume

Explanation:

Density is defined as the mass of a substance per unit volume. The formula for density ($
ho$) is the ratio of mass ($m$) to volume ($V$), so $\text{Density} = \frac{\text{mass}}{\text{Volume}}$. The first option has volume over mass (inverse), the third multiplies mass and volume (incorrect), so the second option is correct.

Answer:

B. Density $=\frac{\text{mass}}{\text{Volume}}$ (assuming the second option is labeled B; if not, the option with $\text{Density} = \frac{\text{mass}}{\text{Volume}}$)
