Question

what is the volume percent of a solution prepared by adding enough water to 200.mL of acetone to make a total volume of 1.60L?

Answer 1

The volume% of acetone = Ml of acetone/Ml of solution x100
ml of acetone =200ml
ml of solution = 1.60 x1000=1600ml

volume% of acetone is therefore= 200/1600 x100= 12.5%
