Firstly, I have just read that at 25degC, 1 out of every 10,000,000 H2O molecules breakes into [itex]H^{+}[/itex] and [itex]OH^{-}[/itex].

If this true, then would this be correct:

Assuming no ionization occurs yet..

If 1 liter of H2O = 1000grams, and 1mol H2O = 18.015g, then by Dimensional Analysis:

[itex][1L*\frac{1000g}{1L}=1000g H2O] => [1000g H2O \frac{1mol}{18.015g}=55.5mol H2O] =>[55.5mol H2O * \frac{6.022E23}{1mol} = 3.3E25 H2O molecules][/itex]

Thus 1 Liter of H2O= 3.3E25 H2O molecules

Then, since 1 out of every 10,000,000 H2O molecules ionizes into [itex]H^{+}[/itex] and [itex]OH^{-}[/itex], then:

[itex]\frac{3.3x10^{25}H2Omolecules}{10^{7}}= 3.3x10^{18} H^{+}ions[/itex]

That number, [itex]3.3x10^{18}[/itex] just feels like it's disproportionately too many [itex]H^{+}[/itex]

Are these calculations correct? Is it correct to divide 3.3E25/10E7 to find the number of H^{+} ions?
