A solution is prepared by dissolving 7.00 g of glycerin (C3H8O3 ) in 201 g of ethanol (C2H5OH) . The freezing point of the solution is _______°C. The freezing point of pure ethanol is -114.6 °C at 1 atm. The molal-freezingpoint- depression constant (Kf ) for ethanol is 1.99 °C/m. The molar masses of glycerin and of ethanol are 92.1 g/mol and 46.1 g/mol, respectively.

Here are some properties of solutions: Homogeneous mixture: A solution is a homogeneous mixture of two or more substances. The particles of a solution are smaller than 10-9 meters in diameter and are too small to be seen by the naked eye. All components of a solution appear as a single phase. Colligative properties: These are the physical changes that occur when a solute is added to a solvent. Colligative properties are determined by the number of solute particles present, as well as the amount of solvent present. Solubility: This is the ability of a compound to dissolve in water. The...

Here are some properties of solutions:
Homogeneous mixture: A solution is a homogeneous mixture of two or more substances. The particles of a solution are smaller than 10-9 meters in diameter and are too small to be seen by the naked eye. All components of a solution appear as a single phase.
Colligative properties: These are the physical changes that occur when a solute is added to a solvent. Colligative properties are determined by the number of solute particles present, as well as the amount of solvent present.
Solubility: This is the ability of a compound to dissolve in water. The maximum amount of a solute that can be dissolved in a certain amount of solvent at a certain temperature is called the solubility of a solute.
Molarity: This determines some of the solution's properties, including freezing point depression and boiling point elevation.
Stability: Solutions are generally very stable, which means that the solute particles do not separate out on keeping.
