When a

⋅
g
mass of dioxygen, the carbon and the oxygen are stoichiometrically equivalent. Of course, the combustion reaction proceeds according to the following reaction:

→

When a

mass of dioxygen, the oxygen is present in stoichiometric excess. The

excess of dioxygen is along for the ride.
The law of conservation of mass,
garbage in equals garbage out
, applies for both examples.
Most of the time, in coal-fired generators, and certainly in the internal combustion engine, carbon oxidation is incomplete, and
C
O
gas and particulate carbon as soot, are products with

when 3.00 g of carbon is burnt in 8.00g of oxygen then the mass of carbon dioxide formed =11.00g
according to the law of conservation of mass the total mass before and after the reaction remains same.
3.00g +8.00g =11.00g
SO LIKEWISE
when 3.00 g of carbon is burnt in 50.00g of oxygen then the mass of carbon dioxide formed =53.00g
according to the law of conservation of mass the total mass before and after the reaction remains same.
3.00g +50.00g =53.00g
