PLEASE HELP ME WITH THIS ONE QUESTION

Answer:

\lambda=1.39\times 10^{-4}\ s^{-1}

Explanation:

Given that,

The half-life of Barium-139 is 4.96\times 10^3

A sample contains 3.21\times 10^{17} nuclei.

We need to find the decay constant for this decay. The formula for half life is given by :

T_{1/2}=\dfrac{0.693}{\lambda}\\\\\lambda=\dfrac{0.693}{T_{1/2}}

Put all the values,

\lambda=\dfrac{0.693}{4.96\times 10^3}\\\\=1.39\times 10^{-4}\ s^{-1}

So, the decay constant is 1.39\times 10^{-4}\ s^{-1}.
