Radioactive decay of 40K atoms in an igneousrock has resulted in a ratio of 25 percent 40K
atoms to 75 percent 40Ar and 40Ca atoms.
How many years old is this rock?
(1) 0.3 10^9 y (3) 2.6 10^9 y
(2) 1.3 10^9 y (4) 3.9 10^9 y

The age of the rock is mathematically given as

t= 2.6 10^9 y

What is the age of the rock?

Question Parameter(s):

a ratio of 25 percent 40K

atoms to 75 percent 40Ar and 40Ca atoms.

Generally, the equation for the half lif is mathematically given as

$t= \frac{ t_{ (1)/(2) } }{ln(2)} ln( ( K_(f) + ( Ar_(f) )/(0.109) )/( K_(f) ) )$

Therefore

$t= (1.251* 10^(9) )/(ln(2)) ln( (0.25+ (0.75)/(0.109) )/(0.25) )$

t= 2.6 10^9 y

In conclusion, the age of the rock is

t= 2.6 10^9 y
