1.5 ppm is 1.5 grams in 1E6 g solution. You want 5.1E6 g solution so you want
1.5 g x (5.1E6g/1E6g) = 7.65 grams solution.
Technically that solution will be made up of 1,000,000 g solvent - 7.65g = 999,992.35g solvent + 7.65g Cl2.
How many grams of chlorine gas are needed to make 5.10 × 106 g of a solution that is 1.50 ppm chlorine by mass?
