# Theoretical Yield Formula – Equation and Problem Solved with Example Published

on

The quantity of a product that is released from the reaction is usually expressed in terms of yield. And the amount that is predicted by stoichiometry is named as the theoretical yield whereas the real amount is actual yield here. The reaction yield is also given as the percent yield and it can be calculated as the percentage of the theoretical amount. The formula for percent yield in mathematics could be written as –

### Theoretical Yield Formula

$\ Percent\;Yield = \frac{Actual\;Yield}{Theoretical\;Yield} \times {100}$

As soon as you will rearrange the formula then the theoretical yield can be calculated quickly. Before you start with some chemical reaction, this is necessary to check how product can be produced by given quantities of reactants. This is a wonderful strategy to calculate the percent yield or theoretical yield of a reaction. In the same way, you can also check the total amount of reagents needed to produce a given amount of the product.

First, you should balance the chemical equation then calculate the total number of moles between reactants and the products. Now calculate the theoretical yield of the chemical reaction, you have enough information now to calculate the value. Just follow then step by step and you ill find the result quickly.

You should know how to find the moles for a chemical reaction and the conversion between moles and gram and the vice versa. With a little understanding, you can understand the chemical reactions better and find the value of theoretical yield or percent yield as needed.
