The half-life of 19O is 29 s. Suppose that a scientist wishes to incorporate 19O into a molecule and then use its radioactivity to trace the fate of that molecule in a reaction. To make an accurate measurement, there must be at least 1.50 mg of 19O left by the end of the study. Which will take 2.5 min each time the experiment run. What is the minimum mass of 19O that must be used each time the experiment conducted?
