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?

The osmotic pressure of an aqueous solution of a certain protein was measured in order to...
The osmotic pressure of an aqueous solution of a certain protein was measured in order to determine the protein’s molar mass. The solution contained 3.50-g of protein dissolved in sufficient water to form 5.00-L of solution. The osmotic pressure of the solution at 25oC was found to be 1.54-mmHg. (Hint: Remember to convert mmHg to atm) Calculate the molar mass of the protein.
