mols CaCO3 = grams/molar mass
Convert mols CaCO3 to mols CO2 using the coefficients in the balanced equation.
Convert mols CO2 to grams. g = mols x molar mass. That is the theoretical yield.
Limestone (CaCO3) emits CO2 gas when exposed to HCl. What is the theoretical yield of CO2 if 56.1
grams of limestone is completely dissolved in HCl?
CaCO3(s) + 2 HCl(aq) R CaCl2(aq) + CO2(g) + H2O(l)
a. 21.5 g
b. 4.16 g
c. 9.53 g
d. 24.7 g
