The nuclei Th232 has a half life of 1.411010 years. Its radioactive decay leads to stable isotope Pb208. A piece of rock contains 3.65 gm of Th232 and 0.75 gm of Pb208. Assuming that all the Pb208 has been produced by the decay of Th232 and all other half lives in the chain are negligible, the age of the rock sample is x109 years (Upto two decimal places)
