Concept explainers
(a)
Interpretation:
Approximate molar mass of the compound has to be calculated.
Concept introduction:
Freezing point depression:
The lowering of the vapor pressure of a solvent by a solute leads to a lowering of the freezing point of the solution relative to that of the pure solvent. This effect is called as the freezing point depression. The mathematical relationship is given below.
Where,
(b)
Interpretation:
When the empirical formula of the compound is
(c)
Interpretation:
More accurate molar mass of the compound has to be calculated
