1. First, this has no answer since you don't know if the solute is ionic or not.Also, I don't know much about the morality of solution. I do know about molality. Assume it is non-ionic, then
dT = Kb*m
dT is 0.633, you know Kb, solve for m.
dT = Kb*m
dT you know, Kb you know.
m = mols/Kg solvent. mols you get from grams/molar mass and kg solvent is 0.058 L.
dT = Kb*m
dT 2.12. Substitute and solve for m = molality. Then m = mols/kg solvent. You know m and kg solveent , solve for mols. Then mols = grams/molar mqass. You know mols and grams, solve for molar mass.
Same as 3 and 4 except you will solve for grams and not molar mass in the last step
Post your work if you get stuck.
