Suppose 2.0g of Compound A and 6.5g of Compound B are consumed in a reaction that produces only one product, Compound.
Calculate the theoretical yield of C. Round to the nearest 0.1 g.
Suppose 6.3g of C are actually isolated at the end of the
reaction.
What is the percent yield of Compound C?
Round your answer to the nearest whole percent.
.
Homework Answers
1)
Use conservation of mass:
mass of product formed = mass of reactant
So,
mass of C = mass of A + mass of B
= 2.0 g + 6.5 g
= 8.5 g
Answer: 8.5 g
2)
% yield = actual mass of C * 100 / theoretical mass of C
= 6.3 * 100 / 8.5
= 74 %
Answer: 74 %

Black Forest Biologicals, a biotech startup, has a promising Alzheimer's drug candidate Compound SLT-88 entering Phase I trials this year. SLT-88 is the only product formed by the reaction of two precursor compounds A and B, both of which are quite expensive. The chief medicinal chemist of Black Forest is trying out different reaction conditions to minimize the cost of manufacturing SLT-88. In the table below are listed the initial and final amounts of A and B used under two...
