Problem
Sodium carbonate reacts with hydrochloric acid according to the equation 2 HCl + Na₂CO₃ → 2 NaCl + H₂O + CO₂. If 35.00 mL of 0.150 M HCl is required to reach the end point when titrating 20.00 mL of a Na₂CO₃ solution, what is the molarity of the Na₂CO₃ solution?
(a) 0.075M
(b) 0.262M
(c) 0.131M
(d) 0.095M
