Tums® tаblets cоntаin cаlcium carbоnate (CaCO3), which neutralizes stоmach 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 CaCl2 will form? Hint: molar mass of CaCl2 is 110.98 g/mol
