What mass of ammonium chloride is formed from 25.0 g of ammonia?

The answer to your question is 77.94 g ≈ 78 g

Explanation:

Data

mass of ammonia = 25 g

mass of ammonium chloride = ?

Balanced chemical reaction

                  HCl  +  NH₃   ⇒   NH₄Cl

             Reactants     Elements    Products

                    1                    Cl               1

                    1                     N               1

                    4                    H               4

The reaction is balanced

- Use proportions to solve this problem

molar mass of ammonia = 14 + 3 = 17

molar mass of ammonium chloride = 14 + 4 + 35 = 53 g

                  17 g of NH₃ 53 g of NH₄Cl

                  25 g of NH₃  x

                 x = (25 x 53) / 17

                 x = 1325/17

                x = 77.94 g
