Question: a What is the decay constant of fluorine 17 if its

(a) What is the decay constant of fluorine-17 if its half-life is known to be 66.0 s?
(b) How long will it take for the activity of a sample of 17F to decrease to of its initial value?
(c) Repeat part (b), but instead determine the time to decrease to an additional to of its initial value. Does it take twice as long to decay to compared to of its initial activity? Explain.
