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

2. An 84 kg University of Toledo groundskeeper who is spraying a 100 mg/L solution of the insecticide dieldrin (MW = 381; logP = 4.56) on some trees exposes 100 cm“ of his skin to the solution over a 4 hr period. Dieldrin has a half-life of about 6 months, a volume of distribution of about 40 L/kg, and a dermal permeability of about 3 x 10° cm/sec. (a) Estimate the absorption rate during the exposure period assuming the blood concentration is much lower than the skin concentration (i.e., take the blood level to be zero in the skin absorption equation). (b) Estimate how it takes after exposure begins for the groundskeeper's plasma dieldrin levels to reach 1 ng/L. (c) Estimate the maximum plasma dieldrin concentration in ng/L that will occur in this groundskeeper due to this exposure. (d) Estimate how long it will take after exposure ends for the groundskeeper's plasma dieldrin levels to drop back down to 1 ng/L. %3D

E O CHEMICAL REACTIONS 0/3 Cameron V Solving for a reactant in solution One way the U.S. Environmental Protection Agency (EPA) tests for chloride contaminants in water is by titrating a sample of silver nitrate solution. Any chloride anions in solution will combine with the silver cations to produce bright white silver chloride precipitate. Suppose an EPA chemist tests a 200. mL sample of groundwater known to be contaminated with tin(II) chloride, which would react with silver nitrate solution like this: SnCl,(aq) + 2 AgNO,(aq) → 2 AgCl(s) + Sn(NO,),(aq) The chemist adds 23.0 mM silver nitrate solution to the sample until silver chloride stops forming. He then washes, dries, and weighs the precipitate. He finds he has collected 6.8 of silver…
