A generic antacid contains sodium bicarbonate, NaHCO_(3), as its active ingredient. A student added a 2.000g sample of the
antacid to a beaker that contained 20mL of 5% vinegar and 15mL of water. Before the antacid sample was added to the beaker,
the mass of the beaker with the water and vinegar solution was 229.120g. When the reaction was complete, the mass of the
beaker and its contents was 230.543g.

How many grams of NaHCO_(3) were in the sample of the antacid? Assume NaHCO_(3) was the limiting reactant in the reaction.
The molar mass of CO_(2) is 44.009(g)/(m)ol and the molar mass of NaHCO_(3) is 84.006(g)/(m)ol.
What was the mass percent (%(m)/(m)) of NaHCO_(3) in the 2.000g antacid sample?
The antacid TUMS contains calcium carbonate, CaCO_(3), as its active ingredient. A student added a 1.310g TUMS tablet to a
beaker that contained 20mL of 5% vinegar and 15mL of water. Before the tablet was added to the beaker, the mass of the
beaker with the water and vinegar solution was 245.605g. When the reaction was complete, the mass of the beaker and its
contents was 246.656g.
How many grams of CaCO_(3) were in the TUMS tablet? Assume CaCO_(3) was the limiting reactant in the reaction. The molar
mass of CO_(2) is 44.009(g)/(m)ol and the molar mass of CaCO_(3) is 100.086(g)/(m)ol.
