I am doing Stoichiometry in my Chem class, my teacher gave us the answers just with no units and its out of order the problem I'm working on is:
( \/ teacher put a carrot here and wrote calcium chloride)
Carbon dioxide and water are produced in the reaction between calcium carbonate and hydrochloric acid.
My balanced eqation is: CaCO3+2HCl -->CO2+CaCl2+H2O

the problem I am currently stuck on: How many grams of carbon dioxide would be produced in the reaction?

I used mol conversion: 1mol CO2 * 44.008gCO2/1molCO2=44.0GCO2 to be produced

however, the answers that my teacher put does not match my answer as his answers were:
10.7 20.6 22.9 500.8 291.1 9.04 562.7

I already got 20.6 from the previous question that has the same balanced formula: How many grams of calcium carbonate would be needed to react completely with 15.0g of hydrochloric acid.

It would be nice if someone could help with a semi-detailed explanation as to why I dont have the asnwer.
