Hello and thank you for posting your question to Brainmass.
If every day 6.3% of krypton is decayed, this means that we are left at the end of every day with 0.937 of the amount present at the beginning of the day..
Thus, after n days, the amount will be (0.937)^n of the initial amount
Half life is ...
The solution shows how to apply the exponential decay equation to the problem of Krypton disintegration.
