Question

If three molecules of hydrogen react with one molecule of nitrogen how many molecules of ammonia would be formed?

Answer 1

Only 2, just 2. Two.

Answer 2

Answer : The number of molecules of ammonia formed would be, 2.

Explanation :

As per question, when the hydrogen molecule react with nitrogen molecule then it gives ammonia as a product.

The balanced chemical reaction will be :

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

By the stoichiometry we can say that, 1 mole of nitrogen gas react with 3 mole of hydrogen gas to give 2 mole of ammonia gas as product.

The number of molecules of nitrogen gas = 1

The number of molecules of hydrogen gas = 3

The number of molecules of ammonia gas = 2

Therefore, the number of molecules of ammonia formed would be, 2.
