Ok, I'll tell you the answer you want to hear.
Molecular weight of water = 18.015 amu.
So about 55.5 moles of H2O per liter.

Even at STP, water can exist cut back than 0 deg C. it rather is reported as sub-cooling. there is an significant concern in aviation reported as rime icing. Rime is a white or milky opaque granular deposit of ice. It happens on a similar time as supercooled water droplets strike an merchandise at temperatures at or cut back than freezing. aspects favoring the formation of rime are small drop length, sluggish accretion, a extreme degree of supercooling, and speedy dissipation of latent heat temperature of fusion. Rime is a consequence of freezing drizzle and feels like frost in a freezer. Rime icing which kinds on airplane can heavily distort airfoil shape, hence diminishing strengthen and commonly used overall performance. Rime icing is lots greater in all likelihood to type in stratus-type clouds with temperatures between 0°C and minus 22°C. on a similar time as formed in cumuliform-type clouds, temperatures type from minus 9°C to minus 15°C and are observed by sparkling icing it rather is then termed blended icing.

Pure water is pure. How can it have a molarity?
There is no solute. So I would assume zero?

One liter of water at 4°C = 999.9750 grams
MW of water = 18.015 g/mole
so:
(999.9750 grams of water /liter)/(18.015 grams/mole) =
55.508 moles/liter = 55.508M
