A mummy is a corpse whose skin and dried flesh have been preserved by either intentional or
accidental exposure to chemicals, extreme cold, very low humidity, or lack of air when bodies are
submerged in bogs. In 2009, a Scientific Team finds a mummy that contains 1.80 mg of Carbon-14
and 1.08 mg of its stable decay product, Nitrogen-14. Given that the Half-Life of Carbon-14 is 5,730
years, in what year did the person die? HINTS: To find the original mass of Carbon-14, assume that all
of the mass of Nitrogen-14 came from the decay of Carbon-14. You may need to make use of
logarithms.
