Consider a 1.0 g sample of carbon with 14C / 12C of 1.3 x 10-12 .

a) How many atoms does it contain?

b) How many 14C atoms does it contain?

c) What is the activity of the sample?

d) Draw a graph of the number of 14C atoms with time. On your graph, mark the half-life and the time constant.

e) Draw a graph of the activity of the sample with time. On your graph, mark the half-life and the time constant.

f) Calculate how long it will take for the sample to have a 14C / 12C of 1.3 x 10-10 . Does this agree with your graph?

g) Calculate how long it will take for the activity of the sample to decrease to 1.0 % of its original value. Does this agree with your graph?
