Answer :

The percent yield of b in a reaction that uses 25.0 g of starting material a, has a theoretical yield of 2.0g of b, and an actual yield of 17.0 g of b is 11.764%

The percentage yield is experimental to theoretical yield divided by 100

Theoretical yield of 2.0g of b, and an actual yield of 17.0 g of b

So % yield is 2/17x100=11.764

  • The ratio of the experimental yield to the theoretical yield multiplied by 100 gives the percentage yield of a chemical reaction.
  • Generally, the value of percentage yield is less than 100 percent since the actual yield produced after the reaction is frequently smaller than the theoretical value.
