Hi, I just wanted to add a few thoughts about this discussion. I thought your questions showed a lot of thought and don't want to put them down. I simply see you did not receive an actual answer and thought you deserved one after all that hard work.
I think that there is more to the math than is being explained here, and the expert reply is no more informed the question. I wish you had received a more honest "I have no idea", as you did from the first person you asked. The main problem I see is that the term mole and gram are both being used in a similar manner. You can't really compare moles of different substances like this. There is no conversion to translate moles to grams. This is because every different molecule has a different molecular weight. For example, a mole of carbon weighs 8 grams. A mole of oxygen weighs 16 grams. To find the molecular weight (how much 1 mole weighs) of a particular substance you have to know it's chemical composition. Then you simply add up the molecular weights of the component elements. For example, water (chemical formula: H20), contains 2 hydrogen atoms and one oxygen and therefore has a molecular weight of 18 (2 x 1g + 16g = 18). That means one mole of water weighs 18g.
Now in order to discuss the moles of fat, you would have to know the exact chemical formulas for fat. The problem is there are hundreds (thousands?) of different fat molecules. The same goes for protein and doubly for carbs. Therefore the calculations on moles of fat or protein or carbs actually mean almost nothing in real life. One gram of fat from olive oil would be completely different from one gram of fat from chicken. You actually have almost no way to calculate how many moles of fat you might be eating in any given meal so doing math on the moles of fat has almost no value for you except as an interesting trivia fact.
Just for fun, the chemical formula for adenosine 5'-triphosphate (atp) is C10H13N5O13P3Na3. The molecular weight can actually vary from about 500 - 600 grams per mole depending on which form is present. On top of that, the efficiency of a particular mitochondria in a given cell to form a particular amount of net atp can vary from person to person, day to day, minute to minute, and from cell to cell. You can't really calculate how much you will get and some atp is used in the cycle to make other atp, and some is wasted.
I hope this is closer to the actual answer that you deserve after spending so much time developing a good question.
