What is the percent by volume of a solution that has 45 mL of ethanol CH3OH dissolved in 255 mL of water?​

Answer:

Percent volume-volume (%(v/v)) = 100 x (volume of solute / volume of solution)

Percent volume-volume (%(v/v)) = 100 x (volume of solute / volume of solution)ex. 20 ml of methanol dissolved in enough water to make 200 ml of solution would result in a 10 % methanol solution

Percent volume-volume (%(v/v)) = 100 x (volume of solute / volume of solution)ex. 20 ml of methanol dissolved in enough water to make 200 ml of solution would result in a 10 % methanol solution-the units may be any units of volume you chose - as long as they are consistent
