The theoretical yield of the CO2 produced is 4.22 g.
The balanced reaction equation is;
2C2H3Cl + 5O2 ------>2CO2 + 2H2O + 2HCl
Number of moles of vinyl chloride = 9.10g /62 g/mol = 0.15 moles
Number of moles of oxygen = 7.80g/32 g/mol = 0.24 moles
Now;
2 moles of C2H3Cl reacts with 5 moles of oxygen
0.15 moles of C2H3Cl reacts with 0.15 moles * 5 moles / 2 moles
= 0.375 moles
Hence oxygen is the limiting reactant;
5 moles of oxygen produces 2 moles of CO2
0.24 moles of oxygen produces 0.24 moles * 2 moles /5 moles
= 0.096 moles
Mass of CO2 produced = 0.096 moles * 44 g/mol
= 4.22 g
