The antacid TUMS® contains calcium carbonate, CaCO,, as its active ingredient. A student added a 1.310 g TUMS tablet to a beaker that contained 20 mL of 5% vinegar and 15 mL of water. Before the tablet was added to the beaker, the mass of the beaker with the water and vinegar solution was 245.605 g. When the reaction was complete, the mass of the beaker and its contents was 246.666 g. How many grams of CaCO, were in the TUMS tablet? Assume CaCO, was the limiting reactant in the reaction. The molar mass of CO₂ is 44.009 g/mol and the molar mass of CaCO, is 100.086 g/mol. mass of CaCO₂: What was the mass percent (% m/m) of CaCO, in the 1.310 g TUMS tablet? % m/m= 28 S

The antacid TUMS® contains calcium carbonate, CaCO3, as its active ingredient. A student added a 1.310 g TUMS tablet to a beaker that contained 20 mL of 5% vinegar and 15 mL of water. Before the tablet was added to the beaker, the mass of the beaker with the water and vinegar solution was 245.605 g. When the reaction was complete, the mass of the beaker and its contents was 246.666 g. How many grams of CaCO, were in the TUMS tablet? Assume CaCO, was the limiting reactant in the reaction. The molar mass of CO₂ is 44.009 g/mol and the molar mass of CaCO, is 100.086 g/mol. mass of CaCO₂: What was the mass percent (% m/m) of CaCO, in the 1.310 g TUMS tablet? % m/m = g
