Hi, so to solve for this, we will calculate the amount of energy released or produced using this equation, the number of moles of methane multiplied by the enthalpy of the reaction.
00:14
So plug in the information that we have.
00:16
If we have one kilogram of methane, that's ch4.
00:20
Let's convert this to grams first.
00:22
One kilogram is 1000 grams.
00:25
And then we will divide the molar mass of methane, 16 .05 grams.
00:30
And then we have here moles of ch4.
00:34
And as per the given enthalpy of reaction, we have negative 861 .3 kilojoules.
00:41
This is per mole of ch4 reacted.
00:45
So we could cancel some units, kilograms, grams, moles of ch4, and the remaining unit will be kilojoules...
