I think that the answer is 1/8 Hope this helps!!!! :D
The correct option is A) 1/8
half-life of tritium, or hydrogen-3, is 12.32 years.
After about 37 years,
= 37/12.32
= 3
means 3 half lives.
sample of tritium that will remain unchanged will be:
= 1/2^no.of half lives
= 1/2³
= 1/2 x 1/2 x 1/2 = 1/8
<u> 1/8 remains back</u>
