A piece of chalk (mainly calcium carbonate) is placed in 250. mL of 0.491 M HCl.
All the CaCO3 reacts, releasing carbon dioxide gas and leaving 250. mL of a clear solution.
20.00 mL of the solution is pipetted into another flask.
32.3 mL of 0.0580 M NaOH is required to titrate the HCl remaining in this 20.00-mL portion.
What was the original mass of CaCO3 in the piece of chalk?
