a chemistry lab have 75ml of pure acid which must be diluted to a solution that is 10% acid.
How many milliliters of water should they add?
:
let x = amt of ml of water required
A simple equation based on the amt of acid
75 = .10(x+75)
75 = .1x + 7.5
75 - 7.5 = .1x
67.5 = .1x
x =
x = 675 ml of water required
