(30+V)/(100+V)=.5
30+V=50+.5V
solve for V
This is a really bad problem, chemically speaking, because "acid" is already a solution. Very rarely are acids in pure form.
100mL of a solution contains 30 mL of acid; this is called a 30% acid solution because
part 30
---- = ---- = 0.30.
whole 100
How many milliliters of acid x would need to be added to the solution to turn it into a 50% solution ? (HInt: Adding acid increases both the volume of acid and the volume of the complete solution.)
