Plot the data given in Table 5.3 for oxygen at 0°C to obtain an accurate molar mass for O 2 . To do this, calculate a value of the molar mass at each of the given pressures from the ideal gas law (we will call this the “apparent molar mass” at this pressure). On a graph show the apparent molar mass versus the pressure and extrapolate to find the molar mass at zero pressure. Because the ideal gas law is most accurate at low pressures, this extrapolation will give an accurate value for the molar mass. What is the accurate molar mass?

Study of body parts and their functions. In this combined field of study, anatomy refers to studying the body structure of organisms, whereas physiology refers to their function.
You have started a patient on a new drug. Each dose introduces 40 pg/mL of drug after redistribution and prior to elimination. This drug is administered at 24 h intervals and has a half life of 24 h. What will the concentration of drug be after each of the first six doses? Show your work
a. What is the concentration after the fourth dose? in pg/mL
b. What is the concentration after the fifth dose? in pg/mL
c. What is the concentration after the sixth dose? in pg/mL
