Quicklime (CaO) can be prepared by roasting
limestone (CaCO3) according to the reaction
−!CaO(s) + CO2(g) .
When 2.6 ×10^3 g of CaCO3 are heated, the actual yield of CaO is 1.06 ×10^3 g. What is the percent yield?
Answer in units of %.
You must find the theoretical yield. Follow the steps in this link to find that. Tha link also hows how to calculate %yield.
answer aint here sry
