A sample of wood from an archaeological excavation is dated
A sample of wood from an archaeological excavation is dated by using a mass spectrometer to measure the fraction of 14C atoms. Suppose 120 atoms of 14C are found for every 1.5×1015 atoms of 12C in the sample.
Part A What is the wood's age?
