Question 941631: A chemist needs to create a solution consisting of 70% hydrochloric acid (the other 30% is water). How much pure acid (100% acid solution) should be mixed with 11 mL of a solution with 40% acid in order to get a solution with 70% acid? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = ml of 100% acid

0.04*11 + 1.00x = 0.70*(x + 11)
0.04*11 + 1.00x = 0.70x + 0.70*11
x - 0.70x = 0.70*11 - 0.04*11
0.30x = 0.70*11 - 0.04*11
x = (0.70*11 - 0.04*11)/0.30
x = 24.2
