You can put this solution on YOUR website! A 70% salt solution was diluted with purified water to produce about 50 liters of 55% salt solution.
Approximately how much purified water was used?
:
let x = amt of purified water required
The total is to be 50 liters,therefore
(50-x) = amt of the 70% solution used
:
.70(50-x) = .55(50)
35 - .70x = 27.5
-.70x = 27.5 - 35
-.7x = -7.5
x =
x = +10.7 liters of pure water required
