Yield Question?

Question: If a reaction has a 45% yield and a theoretical yield of 2.50 g, what is its actual yield? .180 g 3.63 g 1.13 g 1.38 g

Answer: The theoretical yield is the optimal yield i.e. one which produces 100% of the desired product. However, in chemistry, few reactions have an 100% yield. In your question, 45% of the max yield (the theoretical yield) is taken into account and therefore, the actual yield is 0.45 x 2.50 g = 1.125 which is roughly equal to 1.13. The answer is 1.13.
