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
