Final answer:

Without specific compounds, we can only outline the general stoichiometry process: determine the balanced equation, convert masses to moles, identify the limiting reactant, and use it to calculate the mass of the product while respecting the Law of Conservation of Mass.

The right answer is d. None of the above

Step-by-step explanation:

To answer this question, we'll follow several steps of stoichiometry. First, we would need to determine the balanced chemical equation for the reaction; however, without knowing the actual compounds involved, we cannot provide a specific equation. Therefore, the next steps are given generally.

Next, we convert the masses of compounds A and B to moles using their molar masses. This is a key step in stoichiometry as chemical equations are based on moles rather than masses.

Once we have the number of moles for each reactant, we compare the mole ratio we have to the mole ratio in the balanced equation to identify the limiting reactant.

The limiting reactant is the one that will be completely consumed in the reaction, thus determining the amount of product that can be formed.

Having identified the limiting reactant, we use it to calculate the number of moles of the product (compound C) using the mole ratio from the balanced equation.

Lastly, we convert these moles back into mass to find the mass of the product, being sure to follow the Law of Conservation of Mass, which states that the total mass of reactants must equal the total mass of products.

The right answer is d. None of the above
