Given information

The mass of ethylene glycol in the solution is .

The volume of ethanol in the solution is .

The density of ethanol is 0.789 g/cm3.

 

Step-by-step explanation

Step 1.

 The elevation in boiling point of the given solution is calculated by using the formula,

(equation 1)

Where,

  •  is the elevation in boiling point.

  •  is the Van’t Hoff factor which describes the number of ions of solute particles in the solution.

  •  is the molality of the solution.

  •  is the molal boiling point elevation constant

The depression in freezing points of the given solution is calculated by using the formula,

(equation 2)

Where,

  •  is the depression in freezing point.

  •  is the Van’t Hoff factor which describes the number of ions of solute particles in the solution.

  •  is the molality of the solution.

  •  is the molal freezing point depression constant
