Percent Yield of Calcium Carbonate Essay - Academicscope

The percent yield was calculated to be approximately 69.1%. This was concluded by dividing the mass of the mass observed in the reaction divided by the mass calculated that was theoretically supposed to be produced; actual yield divided by theoretical yield (appendix A). Conclusion: The percent yield of the calcium carbonate is 69.1%.

Soil Calcium:Magnesium Ratios and Lime Recommendations

1. Percentages of lime particles passing through and retained on a mesh of U.S. Standard sieves (sizes 8, 40, and 60) were used to develop particle fineness factors. Fineness factors were used with calcium carbonate equivalents (CCE) to calculate lime ENM value for calcite and dolomite lime materials (Buchholz, 1993; Missouri Legislature, 1999).

stoichiometry - Finding the percent of calcium carbonate

Therefore, total unreacted moles HCl in the 50 mL that were used overall = 5 * 0.008 = 0.04 mol, subtract that from the 0.05 mol present in 50 mL and get 0.01 mol HCl that reacted. Therefore 0.005 mol CaCO3 reacted, which in turn corresponds to 0.5 grams per 1 gram, so 50% of the tablet is calcium carbonate.
