Situation:
omeli [17]

The half life of the substance is 6.92 days.

<h3>What is the Half life  ?</h3>

Half life can be defined as the time required to reduce the concentration to half of its initial value.

Here the equation given is

\rm N = N_o e^{-kt}

The concentration will reduce to half therefore

\rm   N= \dfrac{N_o}{2}

so,

\rm 39/2 = 39  e^{- 0.1001 * t_{1/2}}

ln 0.5 = - 0.1001 * t(1/2)

-0.693 = -.1001 * t(1/2)

t(1/2) = 6.92 days.

Therefore the half life of the substance is 6.92 days.
