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 at650decays/min.

If a sample from the totem pole contains 235g of carbon and the ratio of carbon-14 to carbon-12 in living trees is 1.351012, what is the age of the pole inyears?

The molar mass of C14 is 18.035g/mol. The halflife of C14is 5730y.
