Answer:
69mol
Explanation:
The balanced chemical equation given in this question is as follows;
N₂ + 3H₂ → 2NH₃
The above balanced equation shows that 3 moles of hydrogen gas (H2) reacts to produce 2 moles of ammonia (NH3).
To convert the given mass of hydrogen to moles, we use the following formula:
mole = mass/molar mass
Molar mass of H2 = 2g/mol
mole = 207/2
= 103.5mol
If 3 moles of H2 produce 2 moles of NH3,
Then, 103.5mol of H2 will produce 103.5 × 2 / 3
= 207/3
= 69mol
