Question

Consider the equation below. N2 + 3H2 = 2NH3
What is the mole ratio of hydrogen to ammonia?

Answer 1

In the equation, There is 3 Hydrogen molecules for every 2 ammonia. So, the ratio would be: H2/NH3 = 3/2

In short, Your Answer would be: 3 : 2

Hope this helps!

Answer 2

Answer: The mole ratio of $H_2:NH_3=3:2$

Explanation:

Mole ratio is defined as the ratio of moles of the chemical species present in a chemical reaction.

In a chemical reaction, it is the ratio of the stoichiometric coefficients.

For the given chemical reaction:

$N_2+3H_2\rightarrow 2NH_3$

Moles of hydrogen gas = 3

Moles of nitrogen gas = 1

Moles of ammonia gas = 2

So, the mole ratio of hydrogen to ammonia = 3 : 2

Hence, the mole ratio of $H_2:NH_3=3:2$
