Question

Caculate the volume of CO2 gas given off at 756 mm Hg and 23C when 150 kg of limestone(CaCO3) is heated until it decomposes according to the following reaction:CaCO3(s)=CaO(s)+CO2(g)

Answer 1

CaCO3 ==> CaO + CO2
mols CaCO3 = grams/molar mass = 150,000 x molar mass CaCO3 = ?
Convert mols CaCO3 to mols CO2\]
Them convert mols CO2 to volume in L at the conditions listed by using PV = nRT.
