Hydrochloric acid HCl reacts with sodium carbonate Na2CO3, forming sodium chloride NaCl, water H2O, and carbon dioxide CO2. This equation is balanced as written:

2HCl(aq)+Na2CO3(aq) = 2NaCl(aq)+H2O(l)+CO2(g)

the questions :

1) What volume of 1.50 M HCl in liters is needed to react completely (with nothing left over) with 0.500 L of 0.200 M Na2CO3?
Express your answer numerically in liters.

2) A 581-mL sample of unknown HCl solution reacts completely with Na2CO3 to form 15.1 g CO2-. What was the concentration of the HCl solution?

Express the molar concentration numerically.
