Question

The energy of the Sun originates mainly from the conversion of hydrogen to helium, and the creation of

each helium nucleus from four protons releases 26.7 MeV of energy, mainly in the form of radiation. What
mass of hydrogen is transformed every second? Compared with the mass of the Sun equal to 1.99 *10E30
kg, what fraction of the Sun’s mass disappears every second?

Answer 1

missing information, how much total energy released /second by sun so you can calculate how many protons become 2 protons and 2 neutrons per second??
