CaO + CO2 ==> CaCO3
mols CaO = grams/molar mass = ?
Use the coefficients in the balanced equation to convert mols CaO to mols CaCO3.
Now convert mols CaCO3 to grams. grams = mols CaCO3 x molar mass CaCO3
mols CaO = grams/molar mass = ?
Use the coefficients in the balanced equation to convert mols CaO to mols CaCO3.
Now convert mols CaCO3 to grams. grams = mols CaCO3 x molar mass CaCO3
