I've got a 1% solution, and I've used 1ml of said solution in 100ml of water to treat it. I need to work out how many ppm are in the original solution and in the water treatment mix?

1ml contains 0.01ml of the active agent so

when you mix it with 100ml of water you have 

101ml of solution and 0.01 of solute

so

the concentrateion witll be

0.01/101 =  9.9*10^-5 = 99*10^-6

 

99 parts per million
