Final answer:
The question involves using stoichiometry to calculate the mass of a reactant required to produce a specified mass of a product, accounting for the reaction's yield.
Step-by-step explanation:
The question at hand revolves around the concept of stoichiometry and the calculation of mass in chemical reactions. Specifically, it is a mass-to-mass conversion problem where the mass of a reactant needed to produce a given mass of product, considering the reaction yield, is to be calculated. The process involves converting the mass of the product to moles using its molar mass, utilizing the mole ratio from the balanced chemical equation to find the moles of the reactant, and then converting those moles back to mass using the reactant's molar mass. An understanding of theoretical yield, actual yield, and percentage yield is also crucial in solving this problem, particularly since the question specifies a reaction yield that is usually less than 100%.
