Suppose 150 mL of a 10.00% by mass solution of sodiumchloride (density 5 1.0726 g cm-3) is acidified with sulfuric acid and then treated with an excess of MnO2(s). Under these conditions, all the chlorine is liberated as Cl2(g). The chlorine is collected without loss and reacts with excess H2(g) to form HCl(g). The HCl(g) is dissolved in enough water to make 250 mL of solution. Compute the molarity of this solution.
