Calculate the freezing point of 250 ml of water containing 7.5 g of sucrose.
For water, Kf=1.86 K kg/mol. The molecular weight of sucrose is 342.3 g/mol.
When a solute is dissolved in a solvent, the freezing temperature is lowered in proportion to the number of moles of solute added. This property, known as freezing-point depression, is a colligative property; that is, it depends on the ratio of solute and solvent ...
The solution provides detailed explanations and calculations for the problem, including a reference source on colligative properties.
