Molar Mass by Freezubg point

    1. The problem statement, all variables and given/known data

    ok, so i had to do this determining molar mass by freezing point depression lab where we had to find the molar mass of an unknown solvent and then try to figure out the identity of the unknown solvent. i calculated my experimental molar mass to be 505.33 g/mol. does anybody know of any solvents that would have a molar mass of anywhere near that?

    Molar mass of solvent or molar mass of solute?

    Figuring out identity of the substance based on molar mass is absurd. When you have several known substances to select from, that can make sense, but as a general method it is a sure way of elaborate failure.
