Neutrinos

The Sun is currently fusing hydrogen into helium. This process happens by two primary means: the proton-proton chain and the CNO cycle. Both processes produce 2 neutrinos and 26.7 mega-electron-volts of energy along with each helium-4 nucleus. Given the Sun's current luminosity, how many solar neutrinos produced by the proton-proton chain and the CNO cycle pass through every square centimeter of the Earth each second?
