Carbon Dating

Correct!

Use the equation we have derived for carbon dating, N(t) = N0 − 0.0001216 t, to answer the following question. It may be helpful to know that the half-life of 14C is 5700 years.

2.

Problem 2- Calculate the age of a fossil

Approximately how old is a fossil with 12 g of 14C if it initially possessed 32 g of 14C?

  D. ≈ 8066 years old
 

It takes approximately 8066 years for 32 g of 14C to decay to 12 g.

Again, this makes sense in light of the half-life. That is, 16 g of 14C would remain after 5700 years and 8 g would remain after 11,400 years.
