The total amount excreted into urine as unchanged drug after an oral tablet (A) of 50 mg was 36.4 mg. After an oral capsule dose (B) of 25 mg the U" was 20.3 mg. Calculate the relative bioavailability of the tablet A with respect to capsule B. If the absolute bioavailability of the oral capsule is determined to be 0.86 calculate the absolute bioavailability of the tablet dosage form. You are required to list the given data, formula and steps for calculations 5.1

Based on the following data, determine the molecular weight of the unknown solute.  Note the "initial freezing point" refers to the freezing point of the solvent as a pure substance while the "final freezing point" refers to the freezing point of the mixture.  Mass Solvent: 15.000 g FPD Constant of Solvent: 4.9  Mass Solute  2.350 g Initial Freezing Point: 85.3oC Final Freezing Point: 82.4oC Your answer should follow the format: a) ΔT b) Molality of the Solution c) mols of solute  d) Molecular weight of Solute

In order to avoid the possibility of 2-hour delays this winter, EKU will be stockpiling de-icing salts to help keep the roads and sidewalks clear. Facility Services has been quoted the following prices:  K2SO4: $5.35/kg MgSO4: $4.55/kg Which salt provides a better value? Support your answer with a calculation.

You have a 20% stock of NaCl, a 30% stock of K2HPO4, 2.5 M NH4Cl and 10 mg/ml stock of ampicillin. a. How many grams of NaCl would you need to weigh out to make up 150 ml of a solution?b.

A 60-year-old woman who weighs 75kg requires a loading dose of an antibiotic to treat an infection. A plasma concentration of 4.5 mg/L of the antibiotic needs to be achieved for optimal therapeutic effectiveness. The volume of distribution (Vd) of this antibiotic is 0.2 L/kg. The salt factor (S) is 0.6 and bioavailability fraction (F) is 1. The antibiotic is available as a 100 mg/mL infusion.Loading dose = Amount of drug in the bodyBioavailability (F) x Salt fraction (S)Amount of drug in the body = Target conc. (C) x Volume of distribution (Vd)How many millilitres of antibiotic infusion need to be administered?State your answer to 1 decimal place.unit- ml
