You can put this solution on YOUR website! A nurse wants to add water to 30 ounces of a 10% solution of benzalkonium
chloride to dilute it to an 8% solution.
How much water should she add?
:
Let w = amt of water required to dilute to 8%
.10(30) = .08(w+30)
3 = .08w + 2.4
3 - 2.4 = .08w
.6 = .08w
w =
w = 7.5 oz of water required

Check this
.10(30) = .08(7.5+30)
3 = .08(37.5)
3 = 3
