If you are giving a quantity of solute in grams and need to convert it to moles divide the grams by?
The molecular weight. So you'll have to calculate that for the solute first. The molar mass of the solute, which is measured in grams/mole.
How is molar mass determined using colligative properties?
You can calculate the molecular mass using freezing point depression or boiling point elevation using the formula: mols solute= change in BP (or FP) x kg solvent / Kb (or Kf) /i Where Kb and Kf are constants and i is number of ions (or 1 if covalent) Then take mols solute (calculated) and divide into grams solute (recorded)
