how many grams of oxygen can be dissolved in water at 25 degrees celsius to prepare a 2500.0 grams of solution with a concentration of 23.5 ppm?

Using relation : 

concentation in ppm = [(grams of O2 (solute) / grams of solution )]*10^ 6

grams of O2 = [ (grams of solution) * (concentation in ppm ) ]  / 10^6

[(2500.0 g) x (23.5 ) ] / 10^6

 = 0.05875 g O2(answer)
