3 pts 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: N No (24/01/2) N, 2 1/2 where N is 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...
