ice, liquid water, and water steam are three phases oof the same substance, meaning, the basic ingredient is water molecule, h2o. ice at 0C has density of 917kg/m^3, liquid at 4C has density of 1000 kg/m^3, and water steam at 100C Has a density of 0.60kg/m^3, all atmospheric pressure. molecular weight of water is 18. Avogadro's number is 6.022 x 10^23. what is the typical distance between water molecules in the liquid phase of water?
