Please help ASAP. Will make brainiest. Please explain the answer. 27. "Smelling salts," which are used to revive someone who has fainted, typically contain ammonium carbonate, (NH4)2,CO3. Ammonium carbonate decomposes readily to form ammonia, carbon dioxide, and water. The strong odor of the ammonia usually restores consciousness in the person who has fainted. The unbalanced equation is (NH4)2CO3(s) ---> NH3(g) + CO2,(g) + H2O(g) Calculate the mass of ammonia gas that is produced if 1.25 g of ammonium carbonate decomposes completely.
