a) The concentration of orciprenaline in the diluted solution in mg/L Calculate the answer by read surrounding text. mg/L (2 decimal places) b) The actual amount of orciprenaline (in mg) in the powder assayed
Orciprenaline (C11H17NO3, 211.258 g/mol) is a bronchodilator used in the treatment of asthma. The BP assay for orciprenaline tablets is described below. Read the following information carefully and answer the questions below. (Record your answers in decimal notation to the indicated significant figures OR decimal places)
ASSAY – 20 tablets weighing 2.5506 g were crushed to a powder. A portion of the crushed powder (0.5489 g) was shaken with 50 mL of 0.1 M HCl, the mixture was filtered and made up to 100 mL. 10 mL of this solution was further diluted to 100 mL with 0.1 M HCl. The measured absorbance of the diluted solution at 276 nm was 0.581. Additional information: A1% = 72.3, stated content = 20 mg
