A deceased person is found by the coronoer to have a cocaine concentration of 50 ng/dL. What is the concentration of cocaine in his blood two hours earlier?

  • Chemistry -

    What is the rate? You must have that in your information somewhere.

  • Chemistry -

    rate is 1.1 ng/dL-hr

  • Chemistry -

    Is this a first order reaction? If so then
    ln(No/N) = kt
    Substitute No and solve for it.
    N = 50
    k = 1.1
    t = 2.
    If this is not a first order decay please repost giving ALL of the information in the problem.
