Chapter 8, Problem 103CP

The therapeutic concentration—the concentration needed to be effective—of acetaminophen ${\text{(C}}_8{\text{H}}_{\text{9}}{\text{NO}}_{\text{2}}\text{,}$ molar mass $\text{151}\text{.2 g/mol)}$ is $\text{10-20 μg/mL}\text{.}$ Assume thatthe density of blood is 1.0 g/mL

1. If the concentration of acetaminophen in the blood was measured at 15 ppm, isthis concentration in the therapeutic range?
2. How many moles of acetaminophen are present at this concentration in 5.0 L of blood?
