2. If the half-life of Francium-233 is 22 minutes, how much time must elapse in order for 60 grams of a 64 gram
sample to undergo decay? In other words, after how many minutes will you only have 4 grams of the original isotope
remaining?

Answer:

88 minutes

Explanation:

64 g  ---> 32g  ---> 16g  ---> 8 g ---> 4 g

So in total, we have 4 half lives to reach 4.0 g

therefore, 4 x 22 minutes = 88 minutes
