A patient’s treatment plan requires two IV solutions to be administered:20% magnesium sulfate, MgSO4, and 10% calcium chloride, CaCl2. Thenurse is concerned, MgSO4 and CaCl2 are listed as incompatible IVsolutions with the risk of solid precipitate formation (image shown toright). Write the chemical equation that predicts the products thatform when combining MgSO4 and CaCl2. Please use the providedsolubility chart to help you determine chemical phases.

Various concentrations of recombinant human insulin were prepared for use standards for an HPLC method. To verify the prepared concentrations, the samples were analyzed by measuring the absorbance at 280 nm in a short path length (5 mm) cuvette. The molar absorption coefficient for human insulin is approximately 5.875 x 10³ M-¹cm-¹. a. Calculate the extinction coefficient in mL mg-¹cm-¹. b. Calculate the concentrations of the following human insulin standards if the measured absorbances and dilutions used are: Standard 1 Standard 2 Abs. (at 280 nm) of Diluted Sample 0.305 0.685 Dilution 145.0 µL sample, 25.0 μL buffer 130.0 µL sample, 40.0 μL buffer

You are presented with the following prescription: Rx Drug Y 175 mg Witepsol H15 q.s. Supply 6 suppositories (using 3 g nominal moulds) When using Witepsol H15, moulds will hold 1.06 times their nominal weight. The displacement value of Drug Y in Witepsol H15 is 1.1. Calculate the mass of Witepsol H15 required to prepare this product. Give your answer to two decimal places.

From a kinetics experiment, the Vmax was determined to be 450µM∙min-1.  For the kinetic assay, 0.1mL of a 0.05mg/mL solution of enzyme was used, and the enzyme has a molecular weight of 125,000 g/mole.  Assume a reaction volume of 700µL.  Calculate the kcat  (in sec-1) for the enzyme.
