Calculating Half-life Question

  1. Oct 13, 2009 #1
    1. The problem statement, all variables and given/known data
    In 1991, hikers found the frozen remains of a man in a glacier in the Alps, near the Austrian-Italian border. Carbon-14 analysis of tissue samples taken from the body revealed that the ratio of carbon-14 was 52.7% of what it was originally. Calculate the age of the body.


    2. Relevant equations
    N = No (1/2) (t/T(1/2))
    (half-life equation)


    3. The attempt at a solution
    First I rearranged N = No (1/2) (t/T(1/2)) and adding the information to it.
    I got t = 5730 yrs [log(0.527) / log(.5)]

    after i did the calculations i found that
    t = 5295 yrs.

    So the age of the body should be approx. 5295 yrs old.

    Can someone confirm please? thanks
