A 30. 0 g/100mL glucose solution is provided for a polarimeter experiment. A student uses this solution to prepare a number of standards needed for a calibration curve. One such solution is prepared by measuring 20. 0 mL of glucose solution and adding 25. 0 mL of distilled water to it. What is the concentration of this solution? 13. 33 % (w/v) 12. 33 % (w/v) 11. 33 % (w/v) 14. 33 % (w/v)

a) 13. 33 % (w/v)
b) 12. 33 % (w/v)
c) 11. 33 % (w/v)
d) 14. 33 % (w/v)
