Given the reaction: n2 (g) + 3h2 (g) 2nh3 (g) what is the mole-to-mole ratio between nitrogen gas and hydrogen gas? (1) 1:2 (3) 2:2 (2) 1:3 (4) 2:3

The balanced equation for the formation of ammonia is as follows;

N₂ + 3H₂ - - - > 2NH₃

stoichiometry is the molar ratio of components in a reaction.

Stoichiometry could be determined using the coefficients of the compounds in balanced reactions.

coefficient of N₂ - 1

coefficient of H₂ - 3

molar ratio of N₂ to H₂ is 1:3

(2) 1:3
