When calcium carbonate is heated strongly, carbon dioxide gas is released.

Question

CaCO3(s) CaO(s) + CO2(g)
What volume of CO2(g), measured at STP, is produced if 14.1 g of CaCO3(s) is heated?

Answer 1

You need to find the arrow key and use it.
mols CaCO3 = grams/molar mass
Using the coefficients in the balanced equation, convert mols CaCO3 to mols CO2. Now convert mols CO2 to grams CO2. g = mols x molar mass
