I was the same person from yesterday. I need help on a question. I don't type very good so I have one of my host family do it for me. so please help us.

Suppose you have a sample of clamshell at a Paleoindian site and you measure the 14C activity of a 100-gram sample of carbon as 320 disintegrations per minute (or 3.2 disintegrations per gram of carbon per minute).

a.What was the activity (in disintegrations per second) for the 100-gram sample at the time it formed?

wouldnt that be 3.2?

b. What is the age of the sample?
well I came up with
t=(1/.693)ln(
I can't figure out what the other numbers should be.

t=(1/lambda)ln(N0/Nt)
