Molarity
The mol is involved in many chemical calculations. And the molar mass mass is calculated from the chemical formula.
Stoichiometry is based on the fact that chemical reactions occur in ratios of moles of all substances. The problem is that there is no device that directly measures moles. We do have a device to measure mass, so molar mass is used in stoichiometric calculations to give results which are measurable.
Stoichiometry is the calculation of the various products and reactants in chemical reactions. The two types are reaction stoichiometry and composition stoichiometry.
When a problem has a label "stoichiometry" on top of it.
