Answer:

The answer to your question is 68 g

Explanation:

Data

mass of H₂ = 12 g

mass of NH₃ = ?

Balanced chemical reaction

               3H₂  +  N₂   ⇒   2NH₃

Process

1.- Calculate the molar mass of H₂

H₂ = 1 x 6 = 6

NH₃ = 2[(14 x 1) + (3 x 1)]

       = 2[14 + 3]

       = 2[17]

       = 34 g

2.- Use proportions to find the mass of NH₃

                 6 g of H₂ --------------- 34 g of NH₃

                12g of H₂ ----------------  x

                        x = (12 x 34) / 6

                        x = 408/6

                        x = 68 g of NH₃
