4. A good number to remember is 1 ppm = 1 mg Pb/1 kg solution so 100 ppm = 100 mg/kg. Your solution is 0.500 kg so that is 50 mg/kg and that is 0.050 g Pb.
16. Total volume is 150 mL + 750 mL = 900 mL
3.40 M x (150 mL/900 mL) = ? M
4. A solution contains 100 ppm of lead. Determine the mass of lead present in 0.500 kg of the solution.
16. While cleaning a toilet, 150 mL of disinfectant solution is poured into a toilet containing 750 mL of water. If the initial concentration of the disinfectant was 3.40 mol/L, determine the new concentration of the solution.
