Question

What quantity of 64% chlorine solution must be mixed with a 29% chlorine solution to produce 5530 mL of 30% solution?

Answer 1

you need 221.2 ml of the 64% and 5308.8ml of the 29%

Explanation:

the formula is (% x v)=(% * v)+(% * v)

so

(0.3 * 5530)=(0.64 * x)+(0.29 * (5530-x))

simplify

1,659= 0.64x + 1,603.7 - 0.29x

1,659=0.35x + 1,603.7

subtract 1603.7 from both sides

55.3=0.25x

divide 0.25 from both sides

221.2=x

subtract

5530-221.2
