How many moles of nitrogen atoms are there in 6 moles of tnt?

To determine the number of nitrogen atoms, we need to know first the chemical formula of TNT. From literature, it has a chemical formula of C7H5N3O6. Then, we relate the atoms of N with the said chemical formula. To convert from moles of N to atoms of N, we use Avogadro's number. It represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. We do as follows:

6 moles C7H5N3O6 (3 mol N / 1 mol C7H5N3O6) (6.022x10^23 atoms N / 1 mol N) = 1.08 x 10^25 atoms N

Therefore, there are 1.08 x 10^25 atoms of nitrogen for 6 moles of TNT.
