The half life of Tritium is 12.4 How long will it take for 25% of a sample of Tritium to decompose?
The half life of Tritium is 12.4 How long will it take for 25% of a sample of Tritium to decompose?
Solution
If 25% decomposes then , 75% remains.
so,
A(t) = Ao*e^(-ln(2t)/12.4)
0.75 = e^(-ln(2t)/12.4)
0.75 = 2t/12.4
2t = 9.3
t = 4.65 years
