2H₂Oâ†’H₃O⁺+OH^-

concentration of H₃O⁺=OH^-=CÎ±
concentration of H₂O=C(1-Î±)

K=(CÎ±)²/C(1-Î±)=CÎ±²

Î±=1.8 x 10^-9 and C=55.56 M

find K

true enough ; ya, standard concentration is 55.56.

How C=55.56 M ?
It is not given in question ?

you know the density of water

I think you can find the concentration of water

Thank you
