Carbon-14 has a half-life of about 5,600 years. Archaeologists analyze a piece of wood found at an ancient village site and determine that, of he initial 100 grams of Carbon-14 in the wood, onl 3.125 grams are left. How old is the wood?
Answered by bobpursley
3.125=100(1/2)^n/thalf

take log both sides...

log(3.125)=2+n/thlaf (log.5)
so solve for n, then grab you calculator and have fun.
