What quantity of 65 per cent acid solution must be mixed with a 25 per cent solution to produce 672 mL of a 50 per cent solution?
:
Let x = qty of 65% solution
It states that the resulting qty is to be 672 ml, therefore
(672-x) = qty of 25% solution
:
A typical mixture equation
:
.65x + .25(672-x) = .50(672)
Find x
