13 moles of NH3 from 19.5 mol of H2 and excess N2.
The balanced chemical equation is given below.
N2 + 3H2 → 2NH3
So, from above equation,
3 moles of hydrogen gas produce 2 moles of NH3.
So, 1 mole of hydrogen gas produce 2/3 moles of NH3.
Then, 19.5 moles of hydrogen gas produce (2/3)×19.5 moles of NH3.
Number of moles of NH3 produced by 19.5 moles of hydrogen gas = 13 moles
The 6.022×1023 of chemical species like atoms, particles, molecules, ions etc is called moles.
