How long would the Suns initial supply of hydrogen last in both seconds and yrs as it fuses 600 bil. k ea. second total H avail. in its lifetime is 1.8x10 to 2nd pwr?
by

1 Answer

Answer :

You are supposed to divide the total amount of hydrogen, by the consumption per second. That will give you the time in seconds. You can then convert that to years, by dividing by the number of seconds in a year.
