CaCO3 ----------> CaO + CO2
When 45 grams of calcium carbonate decomposes, how many grams of calcium oxide are produced?
Answered by DrBob222
mols CaCO3 = grams/molar mass = ?
Using the coefficients in the balanced equation, convert mols CaCO3 to mols CaO.
Now convert mols CaO to grams CaO with g = mols x molar mass = ?
