15. (The following problem is an actual incident) A state pharmacy inspector came to a pharmacy to assay capsules labeled as "erythromycin 500 mg." When the inspector looked at the formulation record, erythromycin stearate 500 mg was formulated. The original Rx was written for erythromycin 500 mg. As a result, the pharmacy was fined for misbranding. How bad was the error? Determine by calculating the percent error. MWerythromycin = 733.93 g/mol MW erythromycin stearate = 1,018.4 g/mol
