Answer 2

Given - Volume of isopropanol - 25 ml

Volume of water - 45 ml

Find - Percent by volume of solution

Solution - To calculate percent by volume, volume of solute and volume of solution is required.

Isopropanol is solute, water is solvent and solution is mixture of isopropanol and water.

So, volume of solution = Volume of solute + volume of solvent

Volume of solution = 25 + 45

Volume of solution = 70 mililitres

Hence, percent by volume = 25/70*100

Percent by volume = 33.3%

Hence, percent by volume of solution is 33.3%.
