How many moles of h2 and n2 can be formed by the decomposition of 0.261 mol of ammonia, nh3?

The moles of nitrogen and hydrogen gas formed are 0.261 moles and 0.783 moles respectively.

Explanation:

We are given:

Moles of ammonia = 0.261 moles

The chemical equation for the decomposition of ammonia follows:

By Stoichiometry of the reaction:

2 moles of ammonia produces 1 mole of nitrogen gas and 3 moles of hydrogen gas

So, 0.261 moles of ammonia will produce moles of nitrogen gas and moles of hydrogen gas

Hence, the moles of nitrogen and hydrogen gas formed are 0.261 moles and 0.783 moles respectively.
