Well, there are 2mol of water.........and approx. 96×1023 individual neutrons.

Explanation:

And in each water molecule, i.e. 1H216O, where we treat the water molecule as AN ISOTOPOMER than contains 8 neutrons, clearly there are 8mol of neutrons.

And a mole, Avogadro's Number, specifies NA, 6.022×1023 individual items of stuff. So we have approx. 16×NA96×1023 individual neutrons.

I really can use mental arithmetic here; the numbers are so impossibly large that near enuff is good enuff.
