Question

What volume of Ethyl Alchohol and water must be mixed together to prepare 250ml of 60% volume by volume solution of Alcohol in the water?

Answer 1

Answer:

60% by volume of alcohol solution means,each 100 ml of solution will have 60 ml ethyl alcohol.

so,250 ml of solution will have

=(60/100)x250=150 ml of ethyl alcohol 

hence in a 250ml solution of 60% by volume of alchohol and water,alcohol should be 150 ml and water should be 100 ml.
