What likely happens to the molar volume of water in a pure water solution compared to...
What likely happens to the molar volume of water in a pure water solution compared to in a 50% ethanol mixture? - In molecular terms, why might molar volume of a species (i.e. water) depend on the mixture it is in? - Since molar volume, a thermodynamic property, changes depending on the solution, what do you expect to be true about other thermodynamic properties in mixtures?
