suppose you have a sample of clamshell at a paleoindian site and you measure the 14c activity of aa 100-gram sample of carbon as 320 disintegretions per scond (or 3.2 disingtegrations per gram of carbon per second).
a. what was the activity(in disitegrations per second) for the 100 gram sample at the time it formed.
b. how do you know this?
c. What is the age of the sample?
