Question

Nitrogen gas and hydrogen gas undergo synthesis to form ammonia gas. If 1.40 g of nitrogen are used in the reaction, how many grams of hydrogen will be needed?

Answer 1

The answer to your question is 0.3 g of H₂

Step-by-step explanation:

Data

N₂ (g) = 1.4 g

H₂ (g) = ?

Balanced Reaction

N₂(g) + 3H₂ (g) ⇒ 2NH₃ (g)

Process

1.- Calculate the atomic mass of nitrogen and hydrogen.

N₂ = 14 x 2 = 28 g

H₂ = 1 x 6 = 6 g

2.- Use proportions and cross multiplication to solve it

28 g of N₂ ------------------- 6 g of H₂

1.4 g of N₂ -------------------- x

x = (1.4 x 6) / 28

x = 0.3 g of Hydrogen
