I believe it is D, all of these. :) I hope this helps! Please tell me if I'm wrong :)
The number of atoms that remains at the said time is 3.76 * 10^11 atoms of Cl-36 and 2.62 * 10^12 atoms of Ar-36.
<h3>What is the half life?</h3>
The term half life is used to explain the time taken for only half the number of radioactive atoms to remain.
Given that;
No = 3 * 10^12 atoms
t1/2 = 3.01 8 10^5 years
t = 9.03 * 10^5 years
Thus;
k = 0.693/3.01 * 10^5
=2.3 * 10^-6 year-1
Now;
N=Noe^-kt
N = 3 * 10^12e^(2.3 * 10^-6 * 9.03 * 10^5)
N = 3.76 * 10^11 atoms
