Calculate the mass percentage of NaCl in a solution containing 1.50 g sodium chloride in 50.0 g of water. Solution Thus: Total mass of solution = 1.50 g + 50.5 g = 51.5 g % NaCl = 1.50g x 100 = 2.91 % NaCl 51.5 g Practice Exercise 3b A commercial bleaching solution contains 3.62 mass % sodium hypochlorite. What is the mass of NaOCI in a 2.5-kg bottle of bleach? Solution This is a relatively easy question. The quoted percentage means that for every 100 g c solution, 3.62 g are the solute, sodium hypochlorite. You can set up a proportion, or note that the percentage is constant: 3.62% = 0.0362 Thus: kg NaOCI = 0.0362 x 2.5 kg = 0.0905 kg NaOCI = 90.5 g NaOCI -OR- 3.62 g 100.0 g X 2500.0 g x = 90.5 g NaOCI
