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?

(a) Estimate the mass of the luminous matter in the known universe, given there are 1011 galaxies, each containing 1011 stars of average mass 1.5 times that of our Sun. (b) How many protons (the most abundant nuclide) are there in this mates? (c) Estimate the total number of particles in the observable universe by multiplying the answer to (b) by two, since there is an electron for each proton, and then by 109, since there are far more particles (such as photons and neutrinos) in space than in luminous matter.
A state-of-the-art proton decay experiment is expected to detect 44% of the proton decays in a body of water. Assuming protons have a lifetime of 1031 years, how many m3 of water would you need in order to see 2 decays per month? (Assume a "month" is one-twelfth of a year.)
A state-of-the-art proton decay experiment is expected to detect 55% of the proton decays in a body of water. Assuming protons have a lifetime of 1031 years, how many m3 of water would you need in order to see 5 decays per month? (Assume a "month" is one-twelfth of a year.) Express your answer in scientific notation using two significant figures (e.g. 13680.3 would be expressed as 1.4*10^4).
