How much water should be mixed with 12 mL of alcohol so as to obtain 12 % alcohol solution ?

Explanation

Volume percent = `("Volume of solute(alcohol)")/("Volume of solution")`
`12% or (12)/(100) = ((12 mL))/("Volume of solution")` or volume of solution = 100 mL
or Volume of water to be added = (100 - 12) = 88 mL
