What is the percentage difference mass loss between a Helium nucleus and 4 protons? My math came out to 99% but I think I did something wrong (this assumes the mass for of 4 protons is 6.6792 x 10^-27kg and a the mass of a helium nucleus is 6.6892e x 10^-27kg (Units need to be in kilograms to use with e=mc^2)

A nuclear fusion reaction in the Sun converts 4 H nuclei to 1 He-4 nucleus. Each Hydrogen nuclei is 1.007825u (an atomic mass unit); one Helium nucleus is 4.00268u. What is the mass lost in the process (in u)? What is the % of the original mass? Write down the equation that determines the energy produced in this process. Calculate the energy created from 1 kilogram of hydrogen fused. (with units kg & m/s, answer will be Joules) The Sun’s luminosity (or power) is 4 x 1026 Watts (=J/s). How many kilograms of hydrogen must be fused every second to maintain this luminosity? (hint: work backwards from the energy per second to the mass released to the amount of hydrogen required, using the results from the previous question.) The Sun’s mass is ~2x1030 kg. If 10% of this is Hydrogen available in the core, how long will the Sun be able to continue fusing hydrogen at this rate? This is considered the Sun's "lifetime". If the Sun is 4.6 billion years old (and assuming it's power…

A particle has γ=2,865. a) Calculate c-v in m/s. If your calculator gives problems, you might want to solve the appropriate equation for c-v or c(1 - v/c) and use an approximation. b) In the previous problem, in a race to the moon, by 3/4ths the distance, light is one or ten meters ahead of the particle. We routinely approximate mass as zero, gamma as infinite, and speed as the speed of light. ("Massless particles" -- gamma and m have to be eliminated from the expressions. Light is a true massless particle.) If a massless particle has momentum 2,910 MeV/c, calculate its energy in MeV.
