Here are the answers for (a), (b), and (c). I am having trouble showing the calculations for these. Can you please show me the calculations that have these answers?(a) 68.5% ; (b) k = 1.05 x 10–4 s–1; (c) Decay rate = 8.8 x 1013 cps; Fluorine-18 (F) has half-life t/2 = 110. minutes. (a) What percentage of F-sample remains after 1.0hour? (b) What is the decay constant, k (in unit s)? (c) Calculate the initial activity (initial rate ofdecay) in count per second (cps) of a 25-ug sample of fluorine-18.4.

Given, Half life of the element (t1/2) = 110 minutes = 110 x 60 s = 6600 s Time…

Answered: Fluorine-18 (5F) has half-life t/2 =…
