The correct process the student should follow is:
Divide the mass of the reactant by its molar mass to find the number of moles of the reactant. Use the chemical equation to find the number of moles of the product. Multiply the number of moles of the product by its molar mass to find the mass of the product.
This approach accurately describes the steps for converting the mass of a reactant into the mass of a product using stoichiometry based on a balanced chemical equation.
