Tums® tablets contain calcium carbonate (CaCO3), which neutralizes stomach acid (HCl). The balanced reaction is:  CaCO3 (s)  +  2 HCl (aq)  ⟶   CaCl2 (aq)  +  H2O(l)  +  CO2 (g) If a patient has 0.200 mol of stomach acid (HCl) to neutralize, and enough Tums were taken to completely neutralize it, how many grams of H2O will form? Hint: molar mass of H2O is 18.02 g/mol
