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.
