Answer:
Theoretical yield = 9.0g
Percentage yield = 67%
Note: The question is incomplete. The complete question is given below:
Suppose 2.5 g of Compound A and 6.5 g of Compound B are consumed in a reaction that produces only one product, Compound C. Calculate the theoretical yield of C. Round your answer to the nearest 0.1 g. Suppose 6.0 g 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. x ?
Explanation:
Theoretical yield is the quantity of a product obtained from the complete conversion of the limiting reactant into product in a chemical reaction.
The limiting reactant is a reactant that is totally consumed when a chemical reaction is completed.
From the given data, 2.5 g of Compound A and 6.5 g of Compound B are consumed in a reaction that produces only one product, Compound C. We can assume that the limiting reactant has been used in the determining the masses of A and B that would both be completely consumed to produce C.
From the law of conservation of mass, sum of the masses of reactants equals the sum of masses of products, therefore:
Theoretical yield = sum of the reacting masses
Theoretical yield = (2.5 + 6.5) g
Theoretical yield = 9.0g
Percentage yield = (actual yield/theoretical yield) * 100%
Percentage yield = (6.0 g / 9.0 g) * 100%
Percentage yield = 67%
