From the law of conservation of mass, the mass of the reactants and products will remain 20 grams.

The combustion of propane occurs according to the reaction;

C3H8 + 5O2 -----> 3CO2 + 4H2O

We know that the reaction is gas phase and occurs according to Gay-Lussac's law of combining volumes.

Hence from the law of conservation of mass, the mass of the reactants and products will remain 20 grams.
