Tritium, or 3h, has a half-life of 12. 32 years. imagine a sample of tritium is prepared. (a) what fraction of the sample will remain 3. 80 yr after its preparation?

Sagot :

(a) 0.807 fraction of the sample will remain 3. 80 yr after its preparation of tritium.

What is half life?

Half life is the time taken for the radioactivity of a substance to fall to half its original value whereas mean life is average lifetime of all the nuclei of a particular unstable atomic species.

So if a radioactive element has a half life of one hour, this means that half of it will decay in one hour. After another hour, half of the remaining material will decay.

Example:

The radioactive isotope cobalt-60, which is used for radiotherapy, has, for example, a half-life of 5.26 years.

Tritium half life = 12.32 (T half)

Formula :

  • N/N₀ = (1/2) ^ t/T        (N/N₀ = Fraction ratio)
  • t = 3.84
  • T = 12.32
  • N/N₀ = (1/2) ^ 0.308
  • N/N₀ = 0.807

(a) 0.807 fraction of the sample will remain 3. 80 yr after its preparation of tritium.
