Stoichiometry relates moles of reactant to moles of product, so if you have the amount of reactant in the equation, you can calculate the amount of product produced.
The coefficients give the ratio of moles reactant to moles product.

Limiting reactants are the reactants that are used up first. And once they are used up, they stop, or limit, the reaction. So the amount of product that can be produced depends on the limiting reactant. The other reactant, the one in excess, would predict a larger amount of product. But once we produce the amount of product predicted by the limiting reactant. The limiting reactant is used up and the reaction stops.
Stoichiometry is used to find the molar ratios between the reactants of a chemical reaction.

If you know how many you have put in, you know how many you should get out (in theory; yield is often nowhere near the perfect result).

The theoretical amount of product produced.
The theoretical yield of a reaction is the amount of some product, usually given in mass units of grams, that you would expect to get if the reaction based on a stoichiometric calculation not actually "running" the reaction in the laboratory. The actual yield is just that,it is the actual amount of product, in grams you actually produced after really running the experiment in the lab.Actual yield data comes from experimentally determined results. You can not "calculate" it.
It measures the amount of reactants actually produced in a reaction compared to the amount that would theoretically be produced if 100% of the reactants were converted to products according to the stoichiometry of the reaction. It is found by: actual moles of products ÷ predicted moles of products * 100%
The amount of product is determined by the limiting reactant. Once one reactant is used completely, no more product can be produced.
The value obtained when an equation is used to calculate the amount of product that will form during a reaction is called THE THEORETICAL YIELD.
Variable cost is cost that varies with amount of production. In order to classify this cost, you must be able to decide if the cost can be directly related to the product. If it can, then calculate the total cost then divide it by the number of units produced.
