You take a course in archaeology that includes field work. An ancient wooden totem pole is excavated from your archaeological dig. The beta decay rate is measured at 690 decays/min. If a sample from the totem pole contains 235 g of carbon and the ratio of carbon-14 to carbon-12 in living trees is years 1.35 x 10-12, what is the age t of the pole in years? The molar mass of 14C is 18.035 g/mol. The half-life of 14C is 5730 y.
