I assume you mean CaO and CaCO3
I am not certain what heated strongly means.
If one heats CaCO3, CaCO3>>CaO+ CO2
This is the way quicklime and cement is made.
So, if this is the reaction, you got 4 grams (molesCO2=4/44) CO2.
so if you got 1/11 moles CO2, you must have decomposed 1/11 moles CaCO3. How many grams is that?
