# Question #3e2ee

The formula for density is Density = $\frac{M a s s}{V o l u m e}$, which you can abbreviate to D = $\frac{M}{V}$.

Here, we are given the Density (0.714 $\frac{g}{L}$) and the Volume (25.0L). Plugging into the equation we have:

$0.714$$\frac{g}{L}$ = $\frac{M}{25.0 L}$

To solve for the unknown (in this case, M), multiply both sides of the equation by $25.0 L$ (notice that the units of L cancels out on both sides, and we are left with the units we want: grams).

We are then left with:

17.85g = M, so our mass is 17.85 grams.
