A. The weight of 25 tablets of morphine sulfate (150 mg) is 3.075 g. If 0.3075 g was used in the assay and it required 10.3 ml of 0.023N NaOH to back titrate 25 ml of 0.021N H2SO4. Calculate the percent labeled amount of morphine sulfate. Each ml of 1N H2SO4 is equivalent to 758.83 mg of morphine sulfate.
