Moles of incorporated radioelement are known from the measured number of disintegrations per second (disintegrations per second  2 half-life in seconds/Avogadro's number). The total incor- poration rate, expressed in moles of incorporated molecules per time unit and weight unit of total ...
(specific gravity 1.88). Carbon is found in all living things, is insoluble in common solvents,and forms an almost infinite numberof organic compounds. Anaturally occurring radioactive isotope,14C, has a half-life of 5780 years and is used in archaeo logical investigations to date artifacts ...
