6. A radioactive sample has a decay of 0.2193/min. a) What is the half-life? b) If at thestart of an experiment, there are 3.2 x 1015 nuclei present, how much will remain after 1hour?
It is handy to have an equation to quickly determine the number of atoms left in a radioactive sample as a function of time. For this we can divide the initial amount by two for every half-life of time, the following equation does exactly that: No No 2 1/2 (21/2) where Nois the initial number of atoms at t=0, t is time passed and is the half-life. Use the above equation to help you answer the question below. Substance X has a half-life of 10 years, if you start with 1000 grams, how much will be left after 100 years? (Give your answer in units of grams)
