Try this site. By using PV = nRT a solution to your question could be derived however, this is dependent on whether or not you know the values for P, V, and T.
Hope this helps.

In the reaction you describe, there is NO evolution of gas.
Na2CO3 + CaCl2 ===> 2 NaCl + CaCO3
However, if the calcium carbonate then dissociates into calcium oxide and carbon dioxide, then there will be a 1:1 ratio there.
CaCO3 ===> CaO + CO2

The reaction takes place in a closed container.
When the reaction reaches equilibrium (under pressure and high temp). The 2nd reaction reverses back and forth continuously the gas CO2, isn't exactly lost but is instrumental in providing the pressure and is not going to the atmosphere.
However, I'm unsure whether or not the 1st reaction also reverses.
1...Na2CO3 + CaCl2 = 2 NaCl + CaCO3
2...+ heat & CO2 pressure
CaCO3 <=======> CaO + CO2

Find out how many shrubs one mole can eat in say an hour, then leave loads of shrubs near the chemical reaction, come back in an hour, and you should be able to tell how many moles there were by how many shrubs were eaten.
