Question

75 percentage of the radioactive element disintegrates in 24 years calculate the half life of the element

Answer 1

Answer:

12 Years

Explanation:

N = 25%

No = 100%

$\frac{N}{No} = \frac{1}{2} ^{n}$

     = $\frac{25}{100} = \frac{1}{4}$

       $\frac{1}{4} = \frac{1}{2}^{n}$    n = 2

$n = \frac{T}{T^{1/2} }$       $\frac{24}{2} = 12$

Half life of element is 12 years
