Question

Show, in a step by step fashion, your calculations to determine the percent

by volume of a solution that is made by mixing 50 ml of ethanol with 210
ml of water.

Answer 1

The percent by volume of a solution : 19.23%

Further explanation

Given

50 ml of ethanol

210 ml of water

Required

The percent by volume of a solution

Solution

Percent Volume (% v/v) : volume (ml) of solute/100 ml of solution ⇒ ratio of the volume of the solute to total volume of the solution

`\tt \%solute(v/v)=(solute~volume)/(solution~volume)* 100\%`

solute= Ethanol

solvent=water

Solution = solute+solvent

Total volume of the solution :

`\tt =volume~of~Ethanol+solume~of~water\\\\=50~ml+210~ml\\\\=260~ml`

Percent by volume :

`\tt \%volume=(50)/(260)* 100\%\\\\\%volume=19.23\%`
