Question

2)
Tritium has half life of 12.5 years undergoing beta decay.
What fraction of sample of tritium will remain undecayed
after 50 years?​

Answer 1

Answer:

Formula used = N/No = (1/2)^n

Explanation:

Here t = 50 yrs

T(1/2) = 12.5 yrs

So n = t/T(1/2)

= 50/12.5

= 4

N/No = (1/2)^4

= 1/16

So by 1/16 fraction of the sample will remain undecayed....
