Final answer:
The question lacks the necessary context to accurately determine the amounts of sodium acetate stock and sodium chloride stock required. Specific experimental design details or the desired final concentrations are needed to make this determination.
Step-by-step explanation:
The question seems to be missing the necessary context or data to determine how much sodium acetate stock and sodium chloride stock are used. To provide an accurate answer, specific details about the experimental design or the desired concentration and volume of the final solution would be required.
In general, the preparation of a solution will involve measuring a certain amount of stock solution to achieve a desired molarity or molality, which is calculated by using the formula M = moles of solute / liters of solution for molarity or m = moles of solute / kg of solvent for molality.
Without additional information on the intended molarity or molality of the final sodium acetate or sodium chloride solutions, it's not possible to select the correct answer from the options provided: A) 28.3 mL of sodium acetate stock and 20 mL of sodium chloride stock, B) 27 mL of sodium acetate stock and 12.5 mL of sodium chloride stock, C) 15 mL of sodium acetate stock and 12.5 mL of sodium chloride stock, or D) 10 mL of sodium acetate stock and 53 mL of sodium chloride stock.
