It highlights the use of antifreeze, particularly propylene glycol, to mitigate freezing risks. Additionally, it explains the classification of alcohols based on R groups and notes their water solubility, which diminishes with longer carbon chains.

By measuring the freezing point change after dissolving a known mass of solute, one can calculate molality and moles of solute, leading to a calculated molar mass of 59.7 g/mol in an example.

Common salt...This page discusses colligative properties, particularly freezing point depression, and their practical applications like using salts to improve road safety by lowering ice melting points. Common salts include sodium chloride, calcium chloride, and magnesium chloride. The freezing point depression depends on solute concentration and is quantified by the molal freezing-point depression constant, Kf, unique to each solvent.
