Problem
Solid calcium carbonate (molar mass 100.1gmol−1) is added to 25.0mL of 0.500M hydrochloric acid. The reaction proceeds in two steps:
1. CaCO3(s)+2H+(aq)→Ca2+(aq)+H2CO3(aq)
2. H2CO3(aq)→CO2(g)+H2O(l)
Assuming the acid is the limiting reagent, calculate the maximum mass of CaCO3 (to three significant figures) that can be completely consumed.
