Question

How many grams of nitrogen, N2, would be required to react with 6.25 moles hydrogen, H2?

Answer 1

Answer:

2.083 moles of N₂ would be required to react with 6.25 moles of H₂.

Explanation:

Let us first write the balanced chemical equation :

      N₂ + 3H₂ → 2NH₃

Therefore from this equation it is clear that:

3 moles of H₂ require 1 mole of N₂

∵ 1 mole of H₂ requires $\frac{1}{3}$  moles of N₂

∵ 6.25 moles of H₂ requires $\frac{(1*6.25)}{3}$$=2.083$ moles of N₂

MOLE CONCEPT :

The mole is an amount unit similar to familiar units like pair, dozen, gross, etc. It provides a specific measure of the number of atoms or molecules in a bulk sample of matter. A mole is defined as the amount of substance containing the same number of discrete entities (such as atoms, molecules, and ions) as the number of atoms in a sample of pure 12C weighing exactly 12 g. One Latin connotation for the word “mole” is “large mass” or “bulk,” which is consistent with its use as the name for this unit. The mole provides a link between an easily measured macroscopic property, bulk mass, and an extremely important fundamental property, number of atoms, molecules, and so forth.

Answer 2

N₂ + 3H₂ → 2NH₃

moles N₂ = 1/3 x 6.25 = 2.083
