Answer:

C.22 grams because mass cannot be created or destroyed

Explanation:

Reaction equation:

        2H₂  +   O₂    →   2 H₂O

Mass of oxygen  = 18g

Mass of hydrogen  = 4g

The mass of water produced is 22g according to law of conservation of mass.

The law states that " in a chemical reaction, mass is always conserved"

 The sum of the mass of product  and reactants must always be the same.
