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
