Academics

Archeologists can find out the age of artifacts made of wood or bone by measuring the amount of the radioactive isotope 14C present in the object. The amount of isotope reduces in a first-order process. If 19.0% of the original amount of 14C is present in a wooden tool at the time of analysis, explain what is the age of the tool? The half-life of 14C is 5730 yr.
