# How many moles of hydrogen gas, {eq}H_2 {/eq} are needed to produce 1.1 moles of {eq}NH_3 {/eq}? The reaction is: {eq}N_2(g) + 3 H_2(g) \rightarrow 2 NH_3(g) {/eq}

## Question:

How many moles of hydrogen gas, {eq}H_2 {/eq} are needed to produce 1.1 moles of {eq}NH_3 {/eq}?

The reaction is:

{eq}N_2(g) + 3 H_2(g) \rightarrow 2 NH_3(g) {/eq}

## Stoichiometry:

Stoichiometry is a branch of Chemistry and Thermal or Chemical Engineering that involves the numerical relationships between reactants and products or reactants/products themselves in a chemical reaction. It basically determines the relative moles of reactants and products to carry out a chemical reaction.
