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.
3.

Problem 3- Calculate the initial amount of 14C in a fossil

Approximately how many grams of 14C did an organism initially possess if there are 7 g remaining after 17,830 years?

 
B.
≈ 61.2 g
   

An initial sample of approximately 61.2 g of 14C decays to 7 g after 17,830 years.

Again, in terms of the half-life, this answer makes sense since 30.6 g would remain after 5700 years, 15.3 g would remain after 11,400 years, and 7.65 g would remain after 17,100 years.
