Answer 2

(a) Both Assertion and Reason are correct and Reason is the correct explanation of Assertion about volume/volume percentage.

• The mentioned reason states correct formula of volume/volume percentage.
• Volume of solution = 75 + 5
• Volume of solution = 80 millilitres
• Keeping the values of volume of solute and volume of solution in the formula to find volume/volume percentage.
• Volume/volume percentage = 5/80*100
• Hence, Volume/volume percentage of alcohol in water for given concentration = 6.25%
