Calcium carbonate reacts with hydrochloric acid: $CaCO_3(s) + 2HCl(aq) \rightarrow CaCl_2(aq) + CO_2(g) + H_2O(l)$

So, for H2O: (2 * 1) + 16 = 18 g/mol.

And when you finally get the right answer? You realize Jim Clark was never the teacher. He was just the guy who handed you the calculator and showed you where to press. Jim Clark Chemistry Calculations.pdf
