Which is present in all living tissue radio actively decays

Reference no: EM13638871

Which is present in all living tissue, radioactivelydecays via a first order process. A one-gram sample of woodtaken from a living tissue gives a rate of carbon-14 decay of 13.6counts per min. If the half life for carbon-14 is 5720 yrs, how old is a wood sample that gives a rate of carbon-14 decay of 3.9 counts per min?
