Answer:
The correct answer is option B
Explanation:
Given values,
Molarity of
Volume of solution,
Molecular weight of
Substituting this values in Molarity formula, we get
The theoretical yield of a reaction is 28% if 25.0 grams of product were actually produced from a reaction that has a 88% yield .
The theoretical yield of a reaction is calculated in following steps .
Identify the limiting reagent, which is the reagent with the fewest moles.
Divide the fewest number of reagent moles by the stoichiometry of the product.
Multiply the result of Step 3 by the molecular weight of the desired product.
theoretical yield : the maximum amount of product that can be produced from a given amount of reactant. this quantity of product is rarely produced during a chemical reaction. limiting reactant.
