Divide the number of molecules you have by, 6.022 x 10^23. This will give you the moles of water, or the moles of anything, since there is always 6.022 x 10^23 molecules in 1 mole of substance.
1.23x10^24 atoms/6.022x10^23 atom/mole = 2.04 mole H20
Nitrogen is ...19.7
flourine is 80.3...

Hey there!
N₂ + H₂ → NH₃
Balance N.
2 on the left, 1 on the right. Add a coefficient of 2 in front of NH₃.
N₂ + H₂ → 2NH₃
Balance H.
2 on the left, 6 on the right. Add a coefficient of 3 in front of H₂.
N₂ + 3H₂ → 2NH₃
This is our final balanced equation:
N₂ + 3H₂ → 2NH₃
Hope this helps!
