Amount of moles emitted by burning oil

1. The problem statement, all variables and given/known data



Calculate the number of moles of CO2 that are emitted into the atmosphere per year due to the total energy consumption on earth (16TW). Note: 1kg oil yields 42MJ and for oil C:H ' 1:2.



I don't know how to calculate how many grams/moles of CO2 are emitted by burning 1kg of the oil



2. Relevant equations









3. The attempt at a solution



- 1 mole CO2 is 44g



- I calculated that 1,22x10^13 kg oil is needed to cover the 16TW
