Carbon Dating

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.

Problem 1- Calculate the amount of 14C remaining in a sample.

Suppose an organism has 20 g of 14C at its time of death. Approximately how much 14C remains after 10,320 years?

     
 
A.
5.7 g
 
B.
10 g
 
C.
70.1 g
 
D.
