6. (9 points) In the titration of 0.3542 g of pure sodium carbonate (Na2CO3) with hydrochloric acid (HCI) solution, 32.3 mL of HCl solution is required to reach the endpoint in the presence of a methyl orange indicator. The chemical reaction is as follows: Na2CO3 + 2HCl → 2NaCl + H2O + CO2 Accordingly, what is the molarity of the HCl solution? (Na2CO3=106 g/mol)
