About this document
Calculation of ΔT and Moles of Solute by Anonymous pwjbTZTU is a document available to read on EtoBox.
The document calculates the molar mass of an unknown solute based on the temperature change of a solution. It finds that the temperature change was 98.5°C. Using this temperature change and the freezing point constant of 0.51°C/kg mol, it calculates the molality to be 193.14 mol/kg. It then uses this molality and the mass of the solvent to find there were 9.657 moles of solute. Dividing the mass of the solute by the moles gives the molar mass as 1.77 g/mol.
