A 0.0200 M aqueous solution of sodium sulfate solution was prepared in a 50.00-mL volumetric flask. Then 10.00 mL of this solution was transferred to a 100.00-mL volumetric flask and distilled water was added to it until the calibration mark was reached. Then the final solution was homogenized. What was the dilution factor? O a. 2 O b. These answers are all wrong O c. one-tenth (0.1) O d. 10.00 Oe. It cannot be determined because the molarity of the final solution is unknown
