What is the mole to mole ratio between nitrogen gas and hydrogen gas

For instance you have a chemical reaction of N2 + 3H2 -> 2NH3. The number of moles of N2 is 1, H2 is 3 and NH3 is 2. The mole to mole ratio between nitrogen gas and hydrogen gas is 1/3 or 1 is to 3.

Answer : The moles ratio between the nitrogen gas and hydrogen gas are, 1 : 3 respectively.

Explanation :

The balanced chemical reaction will be,

Mole ratio : It is defined as the ratio of the number of moles of the substances whose ratio is to be calculated.

In a chemical reaction, the stoichiometric coefficients represents the number of moles.

By stoichiometry of the reaction we can say that,

1 mole of nitrogen gas reacts with 3 moles of hydrogen gas to produce 2 moles of ammonia gas.

Hence, the mole ratio of between the nitrogen gas and hydrogen gas are, 1 : 3 respectively.
