A student must prepare a solution of HCl whose concentration will be precisely known. He prepares a liter of solution which is approx 0.1M and uses it to titrate precisely weighed samples of Na2CO3. If a .1593gram sample of sodium carbonate requires 31.45ml of HCl solution for complete neutralization, what is the precise concentration of the acid?

Na2CO3 + 2HCl = 2NaCl +CO2+H2O

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) + Na₂CO_3(aq) → 2NaCl_(aq) + H₂O_(l) + CO_2(g)

1) What volume of 1.50 M HCl in liters is needed to react completely (with nothing left) 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.
