One mole of liquid water and one mole of solid

water have different

(1) masses

(2) properties

(3) empirical formulas

(4) gram-formula masses

I believe the correct answer from the choices listed above is option 2. One mole of liquid water and one mole of solid

water have different properties. Although they have the same chemical formula, the molecules are arranged differently causing them to have different set of properties. Hope this answers the question.
