Therefore, the fraction of an original sample of tritium that remains unchanged after 24.62 years will be 1/4.
What is fraction?
A fraction denotes a portion of something larger or, more broadly, any quantity of equal pieces.
Calculation of fraction
Given data:
t = 24.62 years = 25 years.
T = 12.5 years
Fraction can be calculated by using the formula:
N / [tex]N_{0}[/tex] = (1/2) power n..................(i)
n = t / T,......(ii)
Put the value of t and T in fraction equation.
n = 25 / 12.5
n = approx = 2.
Now, using equation (ii).
N / [tex]N_{0}[/tex] = (1/2) power 2
N / [tex]N_{0}[/tex] = 1/4.
Therefore, the fraction of an original sample of tritium that remains unchanged after 24.62 years will be 1/4.
