2 N2 (g) + 3 H2 (g) → → 2 NH3 (g) How many moles of NH3 are produced if 25 mol of H2 reacts?

Question

2 N2 (g) + 3 H2 (g)   → →   2 NH3 (g) How many moles of NH3 are produced if 25 mol of H2 reacts?

Bill R. · Accepted Answer

From the balanced chemical equation, we see that for every 3 moles of H2 consumed there are 2 moles of NH3 produced.

So the math used is as follows

25 moles H2 x 2 moles NH3 = 16 moles of NH3 (16 and 1/3) but 2 sig figs as shown.

3 moles H2
