Chemistry Help? Percent yield

When heated, calcium carbonate decomposes to calcium oxide and carbon dioxide according to the following reaction. CaCO3 -> CaO + CO2

When 60 grams of CaCo3 are heated, the process is expected to form 33.6 grams of CaO and 26.4 grams of Co2- If only 15 grams of CaO and 20 grams of CO2 are formed, what is the percent yield of CaO?

Thanks so much for answering!

Firstly, a "yield" is sort of like an output of produce. Like yield of corn for example. So, the equation for percentage yield is "Theoretical yield (what we SHOULD get), divided by ACTUAL yield, what we ACTUALLY get from the experiment, and because it's a percentage, we multiply by 100%. " It's important that we only consider the product we want.

So, %yield=(Theoretical yield/actual yield)*100%

Later on in school you may be asked to find the theoretical yield, but I don't reccomend you learn it now. So here, %yield=(15/33.6)*100% = 44.6%
