Question

What volume of ethyl alcohol and water must be mixed together to prepare 250 ml of 60 % volume by volume solution of alcohol in 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.

Answer 2

Answer:

Answer is 150ml

As we have 60%by volume

That means 60gm in 100ml of water

Therefore we have volume of h2o as 100ml and total volume of solution is 250ml

Volume left of ethyl alcohol is 150ml

I hope this is the correct answer
