(Calculation) Suppose you're working with a different radioactive species, one that has a half- life of 0.992 hours. You prepare your standard solutions and your unknown, you irradiate the solutions in the Am-Be source and then you count the resulting radioactivity in the scintillation counter. Your results are as follows: Solution # Count rate (CPM) Time Elapsed time (h:mm:ss) 1 143 3:17:39PM 0:11:21 2 190 3:29:00PM 0:20:54 3 274 3:38:33PM 0:27:45 Unknown 358 3:45:23PM 0:33:08 4 370 3:50:47PM 0:38:19 5 373 3:55:58PM 0:43:01 Blank 13 4:00:39PM 0:54:22 Assuming no well correction is required, calculate the corrected count rate Calculate that rate for elapsed time = zero. Give your answer to the closest integer.
