(7) Carbon-14 dating is used in archeology to determine the age of items that were alive or were made from living materials. This works because the proportion of radioactive Carbon-14 to the other isotopes of Carbon is relatively constant in the atmo- sphere. (Volcanos constantly refresh the C-14 content.) A wooden tool from an archeological site is found to contain 22 micrograms of C-14, whereas a similar hnount of modern wood would contain 100 micrograms. How old is the tool?
