Question

10 ml of alcohol is added to water to make up a volume if solution up to 250 ml calculate the percentage of solution

Answer 1

GiveN :

• Volume of Alcohol = 10 mL
• Total Volume of Solution = 250 mL

To FinD :

• Percentage of alcohol in solution

SolutioN :

Volume of Alcohol is given as 10 mL, and it is dissolved in solution of water which and makes total volume as 250 mL. So, use formula Percentage :

⇒Percentage of Alcohol = (Volume of Alcohol/Volume of Water + Volume of Alcohol ) × 100

⇒Percentage of Alcohol = (Volume of Alcohol/Volume of Solution) × 100

⇒Percentage of Alcohol = 10/250 × 100

⇒Percentage = 1/25 × 100

⇒Percentage = 100/25

⇒Percentage = 4

∴ Percentage of alcohol in solution is 4%.
