1. N2 + 3H2 → 2NH3
If you form 5.24 moles of NH3 from the above reaction, how many moles of N2 were
present at the start of the reaction?

Answer 1

Answer: 2.62 moles

Explanation:

For every 2 moles of ammonia that are produced, 1 mole of nitrogen is consumed.

This means that if 5.24 moles of ammonia are produced, 5.24/2=2.62 moles of nitrogen are consumed.
