A nuclear physicist finds 1.0 g of 236 U in a piece of uranium ore and assumes

Question:

A nuclear physicist finds 1.0 μg of ²³⁶U in a piece of uranium ore and assumes it is primordial since its half-life is 2.3 x 10⁷ y.

(a) Calculate the amount of ²³⁶U that would had to have been on Earth when it formed 4.5 x 10⁹ y ago for 1.0 μg to be left today.

(b) What is unreasonable about this result?
