# Which is more: dissociated ions in water or undissociated? [closed]

While studying equilibrium we get to know that there are $1*10^{-7} \ce{~~OH-}$ and $\ce{H+}$ ions in pure water. However, I think there are more undissociated molecules.

[…] there are $1\cdot10^{-7}\ \ce{OH-}$ […] ions
Are you sure that this is an absolute number or rather a concentration in $\mathrm{\frac{mol}{L}}$? IN the latter case, what would be the concentration of undiscociated $\ce{H2O}$ molecules in 1 liter of water?
