To determine the number of moles of nitrogen needed to completely convert a given amount of hydrogen, we need to know the balanced chemical equation for the reaction between hydrogen and nitrogen.
Assuming we're referring to the reaction where hydrogen and nitrogen combine to form ammonia (NH3), the balanced equation is:
N2 + 3H2 → 2NH3
From the balanced equation, we can see that one molecule of nitrogen (N2) reacts with three molecules of hydrogen (H2) to form two molecules of ammonia (NH3).
Based on this stoichiometry, we can calculate the number of moles of nitrogen needed using a mole ratio:
6.34 mol H2 * (1 mol N2 / 3 mol H2) = 2.113 mol N2
Therefore, to completely convert 6.34 mol of hydrogen, we would need approximately 2.113 moles of nitrogen.
