1. The molality of the solution is calculated by dividing the number of moles of solute by the mass of the solvent.
这个溶液的摩尔浓度是通过将溶质的摩尔数除以溶剂的质量来计算的。

2. Increasing the molality of the solute will result in a higher freezing point depression.
增加溶质的摩尔浓度会导致更大的冰点降低。

3. The student was asked to calculate the molality of a solution containing 5 moles of solute and 2 kg of solvent.
学生被要求计算一个含有5摩尔溶质和2千克溶剂的溶液的摩尔浓度。
