Solution-

First, we have 22 kg of gasoline and it consumes 82 kg of oxygen burning it to form carbon dioxide
and water.

Using the law of conservation of mass,
now the total mass of reactants = total mass of products.
We used 22 + 82, or 104 kg. of reactants,

Therefore the total combined mass of products will be the same, or 104 kg.
