Most of the Sun's energy comes from the proton-proton chain in which four hydrogen nuclei (i.e., protons) fuse into one helium nucleus.

(a) Calculate how much mass is "lost" in one proton-proton chain reaction.

(b) How much energy is produced in one proton-proton chain reaction? In other words, find a change in the rest mass energy before and after the reaction.

(c) The total power output of the Sun is 3.85×1026W. If all of it comes from the proton-proton chains, how many kilograms of mass is being converted into energy in the Sun in one second?
