Question: It takes four hydrogen nuclei to create one helium nucleus in the proton-proton chain, which is the main energy source of the Sun. If a single hydrogen nucleus has a mass of 1.6726 x 10-27 kg and single helium nucleus has a mass of 6.6447 x 10-27 kg,
Part A: How much mass is converted into energy to create four helium nuclei?
Part B: How much energy is generated in creating four helium nuclei?
This is a physic question, reply as soon as possible. Thanks.
