Question 783140: a chemist wants to make 150 ml. of a 30% acid solution by mixing a 26% acid solution with a 36% acid solution. how many ml. of each solution should the chemist use? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! percent ---------------- quantity
Acid I 26.00% ---------------- x ml
Acid II 36.00% ------ 150 - x ml
Mixture 30.00% ---------------- 150
Total 150 ml
26.00% x + 36.00% ( 150 - x ) = 30.00% * 150
26 x + 36 ( 150 - x ) = 4500
26 x + 5400 - 36 x = 4500
26 x - 36 x = 4500 - -5400
-10 x = -900
/ -10
x = 90 ml 26.00% Acid I
60 ml 36.00% Acid II
