About this document
Experiment 3 C by sanaerbh792 is a document available to read on EtoBox.
The experiment focused on colligative properties, specifically freezing-point depression to determine the molar mass of an unknown substance. The freezing point of pure naphthalene was measured at 67°C, while the freezing point of the naphthalene solution with the unknown was 69°C, resulting in a depression of 2°C. Calculations revealed the molality of the unknown to be 0.29 mol/kg and its molar mass to be 229 g/mol.
