4-9-SHP-1. Consider a 5.32 g sample of CaCO3 (99.87% pure) in a flask and a 100.0 mL sample of vinegar (5% acidity) in a graduated cylinder. The combined mass of both reagents and containers is 255.98 g. The vinegar is poured into the flask with the calcium carbonate and the following reaction occurs:
CaCO3(s) + 2 HC2H3O2(aq) → Ca(C2H3O2)2(aq) + H2O(l) + CO2(g)
After swirling the reaction mixture for about twenty minutes, the combined mass of the reaction mixture and containers is found to be 254.46 g. What is the percent yield of carbon dioxide in this experiment?
