1. Drug doses are often on the order of 250 mg. Assuming that the medication being taken has a molar mass of 250 g/mole, calculate the number of molecules that would be present in a 250 mg dose.

2. Find an estimate of the number of cells that there are in an average human adult body; provide reference information on the source you used for this estimate.

3. Use your answers to the two previous questions to estimate the number of drug molecules that would be available for each human cell.
