Stoichiometry deals with the relationships between quantities of products and reactants in chemical equations. The fundamental concept is that a balanced chemical equation relates moles of each component of the reaction to each other. The coefficients in front of the various reactants and products show relationships between the reactants and products. Knowing molar masses of those reactants and products allows you to relate the mass of one thing to the mass of any other product or reactant. If you are dealing with things in solution, as long as you can convert the information you have into moles, then the same concept applies.
That's really all there is to stoichiometry. I would suggest that you work with as many different kinds of chemical reactions and problems as you can. Solving stoichiometry problems is conceptually very simple, but the more you practice, the easier it will be.

stoichiometry is the relationship between reactants and products. it can be used to figure how many grams of hydrogen react with 60 grams of oxygen to produce how ever much water.
a simple way to use it is this equation
the given mass divided by the molecular mass of the substance. mulplied by the ration of unknown to know the multiple by the molecular mass of the unkown substance.
Given/Mmass*ration U/K*Mmass of unkown.
