Final answer:
The Sun burns approximately 1.3904 x 10^12 tons of hydrogen in one year, calculated by multiplying the rate of hydrogen burned per second (4.4 x 10^4 tons) by the number of seconds in a year (3.16 x 10^7).
Step-by-step explanation:
The Sun burns approximately 4.4 x 104 tons of hydrogen per second. To calculate how much hydrogen the Sun burns in one year, we need to multiply this rate by the number of seconds in a year. Given that one year is 3.16 x 107 seconds, we can perform the following calculation:
Amount of hydrogen burned per year = Hydrogen burned per second × Number of seconds in one year
Amount of hydrogen burned per year = 4.4 x 104 tons/second × 3.16 x 107 seconds/year
Amount of hydrogen burned per year = 1.3904 x 1012 tons/year
This calculation shows that the Sun burns approximately 1.3904 x 1012 tons of hydrogen in one year.
