Question 391881: a chemist has one solution that is 30% pure salt and another is 60% pure salt. how many ounces of each solution must he use to produce 60 ounces of a solution that is 50% pure salt? Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! a chemist has one solution that is 30% pure salt and another is 60% pure salt.
how many ounces of each solution must he use to produce 60 ounces of a solution that is 50% pure salt?
:
Let x = amt of 60% solution required
then
(60-x) = amt of 30% solution
:
.60x + .30(60-x) = .50(60)
:
.6x + 18 - .3x = 30
.6x - .3x = 30 - 18
.3x = 12
x =
x = 40 oz of 60% solution
:
you can find amt of 30% solution required
