If 50.0 g of sodium bicarbonate is reacted and 11.0 g of carbon dioxide is produced, what is the percent yield of carbon dioxide?

Question

2NaHCO3 --> Na2CO3 + CO2 + H2O

Answer 1

You need to find the theoretical yield to go into this equation.
%yield = (actual yield/theoretial yield) x 100
Theoretical yield can be solved using this example of a stoichiometry problem.
