Fernando is doing his pre-lab homework for Chemistry.  He is asked to predict how many grams of CO2 are produced if 2.09 mol of HCl are reacted according to this balanced chemical equation shown. CaCO3 + 2 HCl → CaCl2 + CO2 + H2O He performs the following calculation.   On the day of the lab his group obtains 35.93 grams of CO2 as their experimental result.  What is their percent yield in standard notation?

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
