# The density of ethyl alcohol is 0.789 g/mL . What is the volume of 35.5 g of eythl alchol?

The volume of ethyl alcohol is 45.0 mL

#### Explanation:

We're going to use the formula below to find the volume:

• I should mention that when you are talking about liquids, the volume will be expressed in terms of milliliters (mL). For solids, the volume will be expressed in cubic meters ($c {m}^{3}$).

We are given the density and mass of ethyl alcohol; so all we have to do is rearrange the equation to solve for the volume:

$V \times D = \frac{m}{\cancel{V}} \times \cancel{V}$

$V \times \frac{\cancel{D}}{\cancel{D}} = \frac{m}{D}$

$V = \frac{m}{D}$

$V = \left(35.5 \frac{\cancel{\text{g")/(0.789cancel"g}}}{m L}\right)$
