A chemistry student needs to determine the concentration of a copper sulfate solution by using mass balance calculations. The student knows that a 100 mL sample of the solution at an unknown concentration was diluted to 500 mL, and then 50 mL of the diluted solution was titrated with a standardized sodium thiosulfate solution. The titre value was 10.0 mL. The student needs to determine the concentration of the copper sulfate solution in terms of grams per liter (g/L).
