The theoretical yield calculator for chemical reactions that calculate theoretical yield of a chemical reactions.
In chemistry, theoretical yield is said to be the quantity of product, which obtained from the complete conversion of the limiting reactant in a chemical reaction. It is said to be the amount of product resulting from a perfect (theoretical) chemical reaction, and that’s why not as same as you will actually get from a reaction in the lab.
However, theoretical yield can obtained under the perfect conditions, these conditions indicates where no product is lost in the process, means:
The theoretical yield equation used in finding theoretical yield from the mole of the limiting reagent, assuming 100 percent efficiency. So, no need to worry more about how to find theoretical yield, the given theoretical yield formula does work best for you!
mass of product = molecular weight of product * (moles of limiting reagent in reaction * stoichiometry of product)
You just have to stick to the following steps to calculate theoretical yield, read on!

Once you added all the above values, simply hit the calculate button, this smart calculator for theoretical yield shows:
Finding theoretical yield becomes easy by identifying the limiting reactant of a balanced chemical reaction. In order to calculate it, the first step is to balance the equation, if it’s unbalanced.
In very next step, you have to identify the limiting reactant (this all based on the mole ratio between the reactants. Remember that the limiting reactant is not found in excess, so the reaction cannot proceed, if once it is used up!
So, to find the limiting reactant, you need to:
To get the grams of product, you have to multiply the moles of each product by its molecular weight.
How to calculate theoretical yield of aspirin, an experiment in which you prepare acetylsalicylic acid (aspirin) from salicylic acid, and you know from the balanced equation for aspirin synthesis in which the mole ratio between the limiting reactant (salicylic acid) and the product (acetylsalicylic acid) is 1:1.
If you have 0.00153 moles of salicylic acid, then the theoretical yield is:
Theoretical yield = 0.00153 mol salicylic acid * (1 mol acetylsalicylic acid / 1 mol salicylic acid) * (180.2 g acetylsalicylic acid / 1 mole acetylsalicylic acid)
Theoretical Yield = 0.276 grams acetylsalicylic acid (aspirin)
