41 O A star converts all its hydrogen to helium, achieving a 100% helium composition. Next it converts the helium to carbon via the triple-alpha process, "He + He + He → 12C + 7.27 MeV. The mass of the star is 4.6 x 102 kg, and it generates energy at the rate of 5.3 x 1030 W. How long will it take to convert all the helium to carbon at this rate?
