So, if you had a fossil that had 10 percent carbon-14 compared to a living sample, then that fossil would be: t = [ ln (0.10) / (-0.693) ] x 5,700 years t = [ (-2.303) / (-0.693) ] x 5,700 years t = [ 3.323 ] x 5,700 years t = 18,940 years old Math Skills Using natural logs (loge or ln): Carrying all numbers to 5 significant figures, ln 30 = 3.4012 is equivalent to e3.4012 = 30 or 2.71833.4012 = 30 A formula to calculate how old a sample is by carbon-14 dating is: t = [ ln (Nf/No) / (-0.693) ] x t1/2 where ln is the natural logarithm, Nf/No is the percent of carbon-14 in the sample compared to the amount in living tissue, and t1/2 is the half-life of carbon-14 (5,700 years).
