Solution

The correct option is A 15
Law of conservation of mass states that the total mass of products formed is equal to the mass of reactants consumed in a chemical reaction.

The mass of reactant = 15 g
From the law of conservation of mass:- The mass of products (new compounds formed) = mass of reactants = 15 g
Hence, the answer is 15 g.
