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.

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.

  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 %.



    Answer  :  

    $\therefore$ 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.



    Answer  :  

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