Answer;
Potassium-40 has a half life of 1.25 billion years.
Explanation;
New amount = Original amount × (1/2)^n ; where n is the number of half lives.
Original amount is 50 atoms
New amount is 25 atoms
Therefore;
25 = 50 × (1/2)^n
1/2 = (1/2)^n
Thus; n = 1
n = 1 which is equivalent to 1.25 billion years
Therefore;
Potassium-40 has a half life of 1.25 billion years.
