Suppose you are designing a proton decay experiment and you can detect 50 percent of the proton decays in a tank of water.

(a) How many kilograms of water would you need to see one decay per month, assuming a lifetime of 1031 y?

(b) How many cubic meters of water is this?

(c) If the actual lifetime is 1033 y, how long would you have to wait on an average to see a single proton decay?
