Question

In a chemical reaction, substance R reacts with compound XY to produce 47.0g of compound RX. If the theoretical yield of RX is 56.0 g, what is the percent yield ?

Answer 1

47/56
And then multiply by 100 to find the percentage
83.9 (to 3 significant figures)

Answer 2

Answer : The percent yield is, 83.928 %

Solution : Given,

Experimental yield = 47 gram

Theoretical yield = 56 gram

The chemical reaction is,

`R+XY\rightarrow RX+Y`

Formula used :

`\% yield=\frac{\text{Experimental yield}}{\text{Theoretical yield}}* 100`

Now put all the given values in this formula, we get the percent yield.

`\% yield=(47g)/(56g)* 100=83.928\%`

Therefore, the percent yield is, 83.928 %
