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 650 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 1.35×10−12, what is the age t of the pole in years? The molar mass of C14 is 18.035 g/mol. The half‑life of C14 is 5730 y. t = ? years
