Your Turn: You are working as a technician for
the State crime lab and you receive a urine sample for
cocaine analysis. The sample is from a driver who fled the
scene of an accident and was apprehended 3 hours later.
It has been 5 hours after the accident when you obtain the
sample and you find a concentration of 6.04 x 10-7 M. The
average removal rate of cocaine from the human body is
0.8 hr-1. The court decides that a concentration above
3.3 x 10-6 M will impair the driver. What was the cocaine
concentration in the driver at the time of the accident?
