As we saw in Section 5.5, a radioactive substance decays exponentially: The mass at time t is m(t) = m(0)e“, where m(0) is the initial mass and k is a negative constant. The mean life M of an atom in the substance is M = -k [" te" dt Jo For the radioactive carbon isotope, "C, used in radio- carbon dating, the value of k is -0.000121. Find the mean life of a 1"C atom.
