if 5.06 g of limestone decomposes by heat to 4.25 g of calcium oxide and carbon dioxide gas,what is the mass of carbon dioxide gas produced?

.....CaCO3 ==> CaO + CO2
.....5.06g.....4.25 + ?
The Conservation of mass says nothing is lost, so 4.25 + ? = 5.06.

I thought about answering this one, but the question reads 4.25g of CaO and CO2; wasn't sure if 4.25g was referring only to CaO or both CO2. I completely agree with DrBob222.
