A 500 g sample ofcarbon taken from the femur of a skeleton is found to have a14Cdecayrate of2000 decays / minute.For currently living organisms, the carbon 14 decay rate is about 15decays/(minute * g)(read: decays per minute per gram of material).a) Find thenumber ofcarbon 14atomsin a500 g sample from aliving organismand the number of carbon 14 atomsremaining in the skeleton's sample.b)If14C has a half-life of5730 years, how old is the skeleton?
