In an ore containing Uranium, the ratio of U²³⁸ to Pb²⁰⁶ nuclei is 3. Calculate the age of the ore, assuming that all the lead present in the ore is the final stable product of U²³⁸ . Take the half-life of U²³⁸ to 4.5 x 10⁹ years

Hello Student,

Please find the answer to your question

Number of atoms of ²³⁸U initially / Numbarof atoms of ²³⁸U finally = 4 / 3 = a / (a - x)

[∵ Initially one part lead is present with three parts Uranium]

∴ t = 2.303 / λ log α / (α – x )= 2.303 x 4. 5 x 10⁹ / 0.693 log 4/3

= 1.868 x 10⁹ years.

Thanks
