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?

An HPLC method was developed for the separation and determination of ibuprofen in blood samples. A 3.00 mL blood sample dissolved in 70.00 mL solvent was prepared and 10.0 mL was injected into the HPLC. Standard ibuprofen solutions were also run.Calculate the ibuprofen present in the 3.00 mL blood sample The following data were obtained.

Volumetric flasks show no intermediate gradations, but they show a single mark to indicate, with high precision, the volume they contain when they are filled to that mark. For most volumetric devices, "filled to the mark" means filled until the bottom of the meniscus of the contents is exactly coincident with the mark. In lab you prepared a standard solution having a concentration of 7 ppm. Using a buret, you transferred the required amount (7 mL) of the 40 ppm stock solution into a 100.0mL volumetric flask, added 2.0 mL sodium citrate solution, 2.0 mL of hydroquinone solution, 3 mL of phenanthroline solution, and diluted with distilled water to the mark. When you were finished, the final volume in your solution was 0.5cm above the mark. The solution you prepared is __________________ Question 7 options: less than 7 ppm because you added less solvent than necessary. greater than 7 ppm because you added less solvent than necessary. less than 7 ppm because you added more solvent than…

In preparing an infusion of the drug cetuximab, a pharmacist adds 15 mL of bacteriostatic water for injection to a vial containing 350 mg of the mAb. The resulting solution contains cetuximab, 24 mg/mL. Loading dose = 4 mg/kg (120 min infusion); maintenance dose = 1.8 mg/kg/wk (60 min infusion) (a) calculate the milliliters of solution required for the loading dose for a 200-lb patient. The pharmacist then transfers the calculated volume into an infusion bag containing 300 mL of sodium chloride injection. Calculate (b) the quantity of cetuximab administered in mg/min and (c) the drip rate, in drops/minute, using an administration set that delivers 15 drops/mL.
