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
