Answer:
option A
Step-by-step explanation:
given,
sample of tritium, ³H
contents present of ³H = 5.25 mol
content of ³He = 6.35 mol
reaction
A₀ is the initial concentration
At is the concentration after time t
A₀ = 5.25 + 6.35 = 11.6 mol
At = 5.25
now,
k = 0.0563 /year
t = 14.1 yr
hence, the correct answer is option A
