Question

N2 + 3H2 mc011-1.jpg 2NH3
What is the mole ratio of hydrogen to ammonia?

Answer 1

1 N₂ + 3 H₂ = 2 NH₃

Mole  ratio  of hydrogen to ammonia :

3 moles H₂  :  2 moles NH₃   or  3 : 2

hope this helps!

Answer 2

Answer : The mole ratio of hydrogen to ammonia is, 3 : 2

Explanation :

Balanced chemical reaction : The chemical reaction in which the number of individual atoms of an element present on the reactant side always be equal to the number of individual atoms of an element present on the product side.

The given balanced chemical reaction is,

$N_2(g)+3H_2(g)\rightarrow 2NH_3(g)$

From the balanced chemical reaction, we conclude that 1 mole of $N_2$ gas react with 3 moles of $H_2$ gas to give 2 moles of $NH_3$ gas as a product.

The mole ratio of nitrogen, hydrogen and ammonia is, 1 : 3 : 2

Therefore, the mole ratio of hydrogen to ammonia is, 3 : 2
