Concept explainers
Interpretation:
The freezing and boiling points of the final solution of ethylene glycol solution which is diluted are to be calculated.
Concept Introduction:
Molarity is the ratio of the number of moles of solute to the liter of solution.
Mathematically, molarity
The concentration of the solution can be expressed in terms of the molality
Molality is the number of moles of solute to the mass of solvent.
The mass of the solvent should be in kilograms
Formula of molality is:
Freezing point is the temperature at which liquid state changes to solid state.
The freezing point depression is:
Here,
molality of the solution in
constant for the solvent.
For water:
The temperature at which vapor pressure of the liquid becomes equal to the
atmospheric pressure is known as boiling point.
The boiling point elevation is:
Here,
molality of the solution in
constant for the solvent.
For water:
