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

Patients undergoing an upper gastrointestinal tract laboratory test are typically given an X-ray contrast agent that aids with the radiologic imaging of the anatomy. One such contrast agent is sodium diatrizoate, a nonvolatile water-soluble compound. A 0.378-m solution is prepared by dissolving 38.4 g sodium diatrizoate (NaDTZ) in.l.60 102 mL water at 3 1.2C (the density of water at 31.2C is 0.995 g/cm3). What is the molar mass of sodium diatrizoate? What is the vapor pressure of this solution if the vapor pressure of pure water at 31.2C is 34.1 torr?

The maximum dose over 24 hours for OTC (over the counter use) of acetaminophen (medication in Tyleonol) is 4,000 mg. Many OTC and prescription medications contain acetaminophen along with other ingredients. Acetaminophen can be found in many cold medicines and in prescription painkillers such as Norco, which also contains the addictive opiod hydrocodone. Keeping track of sources and amount of acetaminophen is very important for your health. Abuse of Norco due to the opiod can also lead to toxic/lethal doses of acetaminophen. There are now strict regulations on the number of tablets of Norco that can be prescribed (7 day maximum per prescription, not refillable without another prescription). A tablet of Norco contains 325 mg of acetaminophen. Thirty tablets are in a week-long prescription post major-surgery to aid in recovery. How many grams of acetaminophen are in the 30 tablets?

1-arr In a study of the gas phase decomposition of phosphine at 120 °C PH3(g)- →1/4 P4(g) + 3/2 H2(g) the concentration of PH3 was followed as a function of time. It was found that a graph of In[PH3] versus time in seconds gave a straight line with a slope of -2.50×10² s1 and a y-intercept of -3.24. Based on this plot, the reaction i v O order in PH, and the half life for the reaction is seconds. zero first second

ASSAY Calibration solutions Calibration solutions of naproxen in the range 5 – 25 μg/mL were prepared. Sample preparation 20 tablets weighing 12.3819 g were crushed to a fine powder. A portion of the powder (145.4 mg) was shaken with approximately 150 mL of acetic acid (0.05 M) for 5 min and then made up to volume in a 250 mL volumetric flask (stock solution). Approximately 50 mL of the stock solution was filtered and a 25 mL aliquot was diluted to 100 mL in a volumetric flask. 10 mL of the resulting solution was further diluted to 100 mL with acetic acid (0.05 M). Analysis The standards and sample solutions were analyzed by HPLC under the following conditions: Column: octadecylsilyl (ODS), 4.6 mmx150 mm, mobile phase: acetonitrile : 0.05 M acetic acid (85:15), flow rate: 1 ml/min, UV detection at 243 nm. Results: A calibration curve of concentration versus peak area was constructed for the standard solutions and gave the straight-line equation: y = 3555.6x + 85, r = 0.9999 The area…
