Suppose you are developing a new pharmaceutical compound. You give a person an IV dose of the chemical at time = 0. You then monitor the blood concentrations at a few time intervals afterwards and obtain the following data:

T = 0 IV injection given (blood concentrations not yet available)

T = 5 minutes C = 460 ppm

T = 120 minutes C = 236 ppm

T = 480 minutes C = 171 ppm

What is the whole-body clearance half-life of the chemical (in units of hours)?

Assume the body is behaving like a two compartment model.
