how much sucrose would need to be burned to match the energy output of the sun?
« on: October 06, 2009, 11:41:22 AM »
The sun's energy output is about 3.83 x 1026 Joules / second. How many
grams of sugar (sucrose, C12H22O11) would have to be burned to match the sun's
hourly output? Explain your work carefully.

honestly, I am not sure where to start. I am trying to teach myself physical chemistry and I am pretty stumped on this problem.

step 1:  look up/calculate the energy released during the combustion of sucrose
