We're given the following reaction:

3 H2(g) + N2(g) → 2 NH3(g)


a) We're being asked to calculate the moles of NH3 that can be produced from 12.0 mol of H2 and excess N2.

From the balanced reaction:  3 moles of H2 produces 2 moles NH3.

moles H2 (mole-to-mole comparison) → moles NH3

moles NH3 = 12 mol H2 ×2 mol NH33 mol H2
