You want delta T = Kf*molality.
You know delta T and Kf, calculate molality.
Then molality = mols/kg solvent.
You know molality and kg solvent, calculate mols.
Then mols = g/molar mass.
You know mols and molar mass, calculate grams.
Can someone please help me ?
What mass of glycerol must be dissolved in 200.0 g of water to give a solution with a freezing point of -1.50?
im not sure how to even start this problem. I think i would find the moles in water first, then the grams in glycerol after?
Pleaseee help!
