4) How much energy is produce when the sun converts 1kg of mass into energy?
5) How much energy is produce when the sun converts 1kg of hydrogen into helium? (Hint: How does this problem differ from problem 4?)
7) Use the luminosity of the sun, the total amount of energy it emits each second, to calculate how much mass it converts to energy each second.

Can someone help me answer these 3 questions?
I cannot seem to come to answer on those 3.
