H1 means hydrogen with mass 1, H2 means hydrogen with mass 2 (has a neutron), etc 1) H1 + H1 -> H2 + positron + neutrino + 1.18 Mev (+0.26MeV) 2) H1 + H2 -> He3 + photon + 5.49MeV 3) He3 + He3 -> He4 + 2*H1 + 12.86 MeV (The neutrino produced in 1 for all practical purposes do not interact with matter, so their energy can be ignored (neutrino energy 0.26MeV) Using the above 3 equations, calculate the energy released per proton. Note that the equations must be properly combined in order to find the overall reaction! Given the sun's luminosity calculate the amount of hydrogen converted to helium every second. How much mass per second is converted directly to energy? 2. Relevant equations sun's luminosity: 3.826*10^26 W answers: 6.55 MeV, 6.2*10^11 kg, 4.3x10^9 kg. 3. The attempt at a solution I have shown each proton has released 6.55 MeV. but how do i calculate the amount of hydrogen converted to helium every second?
