Using sodium carbonate as the primary standard, a solution of hydrochloric acid was analyzed using a titration procedure. A 0.356 g sample of Na2CO3 (molar mass = 106.0 g/mol) required 24.22 mL of HCl solution to reach the stoichiometric point of the titration. Calculate the molarity of the HCl solution. Na2CO3(aq) + 2HCl(aq) ⟶ 2NaCl(aq) + H2O(l) + CO2(g)
