Calcium carbonate was thremally decoimposed . The ensuing gas completely neutraliserd one litre of 0.1N solution of ammonia. Assuming complete decomposition calculate the mass of calcium carbonate decomposed.

I'll give you a start.
CaCO3 will decompose to produce CaO and CO2. The gas is CO2 and equation is already balanced.
The CO2 is bubbled into the ammonia solution, which is really NH4OH. The CO2 reacts with the water as well and forms H2CO3. So now you have the neutralization of the acid and base.
Since you know how much NH3 you start with, you can calculate the amount of CO2 in this neutrlization. Based on that, you can go back to the decomp. reactions and calculate the starting calcium carbonate
