100 sec is it correct?

Assume that it takes 10,000 Joules of energy to raise 100 grams of cake batter from room temperature (23 ∘ C) to 90 ∘ C (fully cooked). How many seconds would it take for a 100-Watt light bulb to output this much energy? Note: 1 Watt = 1 Joule per second. Enter your answer in seconds but without including the unit.
