forsale [732]

Answer:

mean life = 8264.5 s

Step-by-step explanation:

k = - 0.000121

The relation is given by

$m = mo e^{kt}$

Now, the mean life is the life time for which the sample retains.

The mean life is the reciprocal of the decay constant.

The relation between the mean life and the decay constant is

$\tau =\frac{1}{k}\\\\\tau = \frac{1}{0.000121} = 8264.5 seconds$
