No idea what you are doing. You are multiplying some numbers, dropping units to make it impossible to take track of what you are calculating, then you multiply by 3 to get some number that is completely backward (mole contains 6.02×1023, not 10-23 entities). Then you use this number to make some conclusions. I bet you tried to calculate number of atoms by calculating mass of a single atom and the finding how many atoms of a given mass are present in 12 g of carbons. Trick is, to do so you should divide, not multiply.
There is also a very minor mistake - mass of an atom is not equal sum of masses of the components (google for binding energy). But it is not the main source of your problems.
