Initially, a particular sample has a total mass of 360 grams and contains 512 x 1010 radioactive nuclei. These radioactive nuclei have a half life of 1 hour. (a) After 4 hours, how many of these radioactive nuclei remain in the sample (that is, how many have not yet experienced a radioactive decay)? Note that you can do this problem without a calculator 32.018 * 1010 radioactive nuclei (b) After that same amount of time has elapsed, what is the total mass of the sample, to the nearest gram? 22.512 Xg
