A ppm is 1g solute/10^6 g solution.
You want 1.40 ppm and you want 5.40E6 g of that solution; therefore,
(x g solute/5.40E6g soln)*10^6 = 1.40
x = 1.40*5.40 = 7.56 g Cl2.
Then 7.56 g Cl2/5.40E6 g solution = 1.40 ppm
How many grams of chlorine gas are needed to make 5.40 x 10 6 g or a solution that is 1.40 ppm chlorine by mass?
