<s>[INST] The single-dose pharmacokinetics of a drug can be described by the following equation for the concentration of drug in the bloodstream:

C(t) = (D/V) * e^(-kt)

Where:

* C(t) is the concentration of the drug at time t
* D is the dose of the drug administered
* V is the volume of distribution of the drug
* e is the base of the natural logarithm (approximately equal to 2.718)
* k is the elimination rate constant
* t is the time after administration of the drug

A new drug has been developed and its pharmacokinetics have been characterized. The volume of distribution is 10 L, the elimination rate constant is 0.1 hr^-1, and the dose is 200 mg. What is the concentration of the drug in the bloodstream 2 hours after administration?[/INST]
