Answer:
3 mol H2 / 1 mol NH3
Explanation:
Mole ratio depicts or shows the relationship between the number of moles of two substances in a chemical reaction. The following chemical equation is given:
N2 + 3H2 → 2NH3
According to the above chemical equation;
- 1 mole of N2 reacts
- 3 moles of H2 reacts
- 2 moles of NH3 is produced
Hence, this means that according to the options provided in this question, the incorrect one is 3 mol H2 / 1 mol NH3 because 2 moles rather than 1 mol of NH3 is involved.

Answer:
Number of mole in H2O = 5.4 moles
Explanation:
Given:
Mass of H2O = 97.3 gram
Find:
Number of mole in H2O
Computation:
We know that molar mass of H2O = 18 g/mole
So,
Number of mole = Given Mass / Molar mass
Number of mole in H2O = Mass of H2O / Molar mass of H2O
Number of mole in H2O = 97.3 / 18
Number of mole in H2O = 5.4055
Number of mole in H2O = 5.4 moles
