Question

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

Answer 1

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 (`cm^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:

`VxxD=m/cancelVxxcancelV`

`VxxcancelD/cancelD = m/D`

`V= m/D`

Plug in your known values:

`V = (35.5cancel"g")/(0.789cancel"g"/(mL))`

Therefore, the volume is 45.0mL
