What does stoichiometry mean?
Stoichiometry is a section of chemistry that involves using relationships between reactants and/or products in a chemical reaction to determine desired quantitative data. In Greek, stoikhein means element and metron means measure, so stoichiometry literally translated means the measure of elements.
What is the mole ratio of hydrogen to ammonia?
The ‘Moles” are the coefficients of the molecules in the reaction equation. In this equation the coefficient of hydrogen is ‘3’ and the coefficient of ammonia is ‘2’. So, the ratio of hydrogen to ammonia is 3:2.
