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.

An example of stoichiometry is any chemical reaction. HCl+NaOH->NaCl+H2O may be an example of stoichiometry.
Stoichiometry is not a method of measurement, it is a concept for the ratios of reactants and products.
The word stoichiometry derives from two Greek words: stoicheion (meaning "element") and metron (meaning "measure"). Stoichiometry deals with calculations about the masses (sometimes volumes) of reactants and products involved in a chemical reaction. It is a very mathematical part of chemistry, so be prepared for lots of calculator use. Jeremias Benjaim Richter (1762-1807) was the first to lay down the principles of stoichiometry. In 1792 he wrote: "Die stöchyometrie(Stöchyometria) ist die Wissenschaft die quantitativen oder Massenverhältnisse zu messen, in welchen die chymischen Elemente gegen einander stehen." [Stoichiometry is the science of measuring the quantitative proportions or mass ratios in which chemical elements stand to one another.]
There are very many calculations dealing with paediatrics, which will require different kinds of calculation. Without more specific information, the question cannot be answered.
Which drug calculations? The toxic dose, the effective dose, the required dose, the metabolic halflife, the time since consuming and many more calculations require completely different formulae and data.
