Theoretical Yield Calculator
Top
When a chemical reaction takes place completely where none of the reactants are wasted. The amount of products formed in such a reaction is called Theoretical yield. It gives the idea of efficiency of a reaction.
Theoretical Yield Calculator calculates percent yield, actual yield or theoretical yield if any of the two quantities among the three are given.

## Steps for Theoretical Yield Calculator

Step 1 :

Observe the reaction and the given quantities

Step 2 :

Use the formula:

Percentage yield = $\frac{Actual\ yield}{Theortical\ yield}$ $\times$ 100%

Substitute the given values in the above formula to get the desired quantity.

## Problems on Theoretical Yield Calculator

1. ### Find the Percent yield of a product for a given reaction: Cao(s) ---> Cao(s) + Co2(g).If the theortical yield of Cao is 1.15 $\times$ 103 g of Cao and actual yield is 1.005 $\times$ 103 g.

Step 1 :

given: Theortical yield = 1.15 $\times$ 103 g and

Actual yield = 1.005 $\times$ 103 g

Step 2 :

Percentage yield = $\frac{Actual\ yield}{Theortical\ yield}$ $\times$ $\times$ 100%
= $\frac{1.005 \times 10^{3}}{1.15 \times 10^{3}}$ $\times$ 100%.
= 0.8739 $\times$ 100%
= 87.39 %.

$\therefore$ The Percentage yield of Cao reaction is 87.39.

2. ### Find the actual yield of a product for a given reaction: 2 NaHCo3(s) -----> Na2Co3(s) + Co2(g) + H2o(g).If the theortical yield of Na2Co3 is 22.5 g and percent yield is 60 %.

Step 1 :

given: Theortical yield = 22.5 g
Percent yield = 60 %
Actual yield = ?

Step 2 :

Percentage yield = $\frac{Actual\ yield}{Theortical\ yield}$ $\times$ 100%
Actual yield = $\frac{Percentage\ yield \times Theortical\ yield}{100 %}$
= $\frac{60 % \times 22.5}{100 %}$
= 13.5 g.

$\therefore$ The Actual yield of NaHCo3 reaction is 13.5 g.
