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.
5.

Problem 5- Calculate the amount of 14C remaining after a given time has passed

Approximately what percentage of an initial sample of 14C remains after 33,450 years?


 
D.
1.7%
   

Approximately 1.7% of the initial sample remains after 33,450 years.

This makes sense since 50% would remain after 5700 years, 25% would remain after 11,400 years, 12.5% would remain after 17,100 years, 6.25% would remain after 22,800 years, 3.125% would remain after 28,500 years, and 1.5625% would remain after 34,200 years.
