A 25.00 mL sample of HCl(aq) was added to a 0.1000 g sample of CaCO 3 All

Question:

A 25.00 mL sample of HCl(aq) was added to a 0.1000 g sample of CaCO3 All the CaCO3 reacted, leaving some excess HCl(aq).

CaCO3(s) + 2 HCl(aq)→CaCl2(aq) + H2O(l) + CO2(g)

The excess HCl(aq) required 43.82 mL of 0.01185 M Ba(OH)2 to complete the following reaction. What was the molarity of the original HCl(aq)?

2 HCl(aq) + Ba(OH)2(aq)→BaCl2(aq) + 2 H2O(l)
