Question 449727: Hakan has 50 milliliters of a 10% acid solution. How many milliliters of 45% acid solution should he add to create a 35% acid solution? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! 50 ml x .1=5 ml
.45(n)+5=.35(n+50)
.45n+5=.35n+17.5
.1n=12.5
n=125
You need 125 ml of 45% solution to add to 50 ml of 10% solution to make 175 ml of 35% solution..
