Technically, the problem doesn't specify if it is an ionic or a molecular compound. Without that information you can't work the problem. When the problem doesn't say, I always assume it is molecular and not ionic.
delta T = Kb*molality
Solve for molality.
molality = moles/kg solvent.
Solve for moles.
moles = grams/molar mass
Solve for grams.
what is the molecular mass of a solute if a solution containing 150 g of that solute
and 1.0 kg of water has a boiling point of
102.0 degree c? (Kb= 0.512 degree C/m)
