Answer to Question #245660 in General Chemistry for Jascia

Question

How many grams of H₂ can be formed from 89.0 grams of NH₃ in the following reaction?

2 NH₃(g) → 3 H₂ (g) + N₂ (g)

Answer 1

Molar mass of NH₃= 17.031

89/17.031= 5.23moles

Mole ratio of NH₃:H₂

2:3

= 5.23×3/2

= 7.84mol

Molar mass of H2 = 2.016 g/mol

2.016×7.84= 15.8g
