Chemistry question concerning conversions and volumes?

Chlorine is used to disinfect pools. The accepted concentration for this purpose is 1.00ppm Chlorine or 1g Cl for 1 million grams water. Calculate the volume of a solution (in milliliters) a home owner should add to her swimming pool if the solution contains 8.50% Chlorine by m and there are 7.24x10^4 gallons of water in the pool. ( 1 gal = 3.79 Liters; density of liquids = 1.00g/mL).
