The volume of ethyl alcohol is 45.0 mL


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:


#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
