WebMass of the Sun is 1.989 × 10^30 kg The Sun is, at present, about 70% hydrogen and 28% helium by mass everything else ("metals") amounts to less than 2%. This changes slowly over time as the Sun converts hydrogen to helium in its core. The Sun is about 4.5 billion years old. Since its birth it has used up about half of the hydrogen in its core. WebShow that the statement in the text is correct: namely, that roughly 600 million tons of hydrogen must be converted to helium in the Sun each second to explain its energy … WebWe can get a quick estimate by calculating # protons in the Sun ~ (total mass of Sun) / (mass of proton) ~ 2.0 x 10 30 kg / 1.67 x 10 -27 kg ~ 1.0 x 10 57 If we have 10 57 protons to use and we use 10 38 each second, we have enough protons to last for about 10 19 seconds…or over 100,000,000,000 years! meaning of the name lynnette
