DILUTIONS AND STANDARDS

Suppose we wanted to prepare 50 mL of a 100 mg/dL working standard of glucose from the original stock standard of 10 mg/mL. 50 mL needed x 1/10 = 5 mL stock standard . 50 mL needed - 5 mL stock std = 45 mL diluent . Therefore, to prepare 50 mL of working standard, 5 mL of stock standard is added to 45 mL diluent (such as water). ... ................
