1) The molecular mass of a substance was determined by the freezing point depression technique. The minimum data required for the determination are

a. ƒ´Tf and Kf only.
b. ƒ´Tf , Kf and mass of solute.
c. ƒ´Tf , Kf , mass of solute and mass of solvent.
d. ƒ´Tf , Kf , mass of solute, mass of solvent and identity of solvent.
e. ƒ´Tf , Kf , mass of solute, mass of solvent and identity of solvent and solute

I know that I already posted this question but my teacher now told us to assume that the solute is not ionic so I was just wondering if this would change the answer to this problem?

  • Chemistry -

    Yes, if we can assume the solute is not ionic, then it isn't necessary to know the identity of the solute and solvent.
    What's f' stand for?

  • Chemistry -

    Its suppose to be deltaT f. So would the minimum data required be Tf, Kf, and mass of solute?
