In archeology it is known that within the bones of a living human one carbon atom out of 51011 is the unstable isotope 14C (half-life 5700 years), while all the rest are the stable isotopes 12C. Suppose that due to the recent activities in one of the North-African countries a previously unknown ancient burial place was discovered right under the ruins of the deposed leader's residence. While investigating a sample of mass 1 g from the tomb the archeologists registered 100 acts of 14C decay during a 10- minute test interval. Assuming that the sample was pre-processed to ensure it is pure carbon, and recalling that 12 g of carbon contains 6 1023 atoms, evaluate the age of the mummy. |
