In 1991, hikers found the frozen remains of a man in a glacier in the Alps, near the Austrian-Italian border. Carbon-14 analysis of tissue samples taken from the body revealed that the ratio of carbon-14 was 52.7% of what it was originally. Calculate the age of the body.(adsbygoogle = window.adsbygoogle || []).push({});

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

t1/2 is the half-life of carbon-14 (5,700 years).

Is that right?
