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?
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?
Its suppose to be deltaT f. So would the minimum data required be Tf, Kf, and mass of solute?
Calculate the mass of solute of glucose per 300 ml which molar mass is 180
