# How to Calculate and Solve for Van’t Hoff Factor, Ebullioscopic Constant, Molality and Boiling Point Elevation | The Calculator Encyclopedia

The image above represents boiling point elevation. To calculate the boiling point elevation, three parameters are needed and these parameters are Van’t Hoff’s Factor (i), ebullioscopic constant (Kb), and Molality.

The formula for calculating boiling point elevation:

Î´TbÂ = iKbÂ x Molality

Where;
Î´TbÂ = boiling point elevation
i = Van’t Hoff’s Factor
KbÂ = ebullioscopic constant
Molality

Let’s solve an example;
Find the boiling point elevation when Van’t Hoff’s Factor is 42, the ebullioscopic constant is 60, and molality of 180.

This implies that;
i = Van’t Hoff’s Factor = 42
Kb = ebullioscopic constant = 60
Molality = 180

Î´TbÂ = iKbÂ x Molality
So, Î´TbÂ = (42)(60)Â x 180
Î´TbÂ = (2520)Â x 180
Î´TbÂ = 453600

Therefore, the boiling point elevation is 453600 Â°C m-1.

### Calculating the Molality using the Boiling Point Elevation, Van’t Hoff’s Factor and Ebullioscopic Constant

Molality = Î´Tb / iKb

Where;
Molality
Î´TbÂ = boiling point elevation
i = Van’t Hoff’s Factor
KbÂ = ebullioscopic constant

Let’s solve an example;
Find the molality with a boiling point elevation of 120 and a van’t hoff’s factor of 32 with an ebullioscopic constant of 12.

This implies that;
Î´Tb = boiling point elevation = 120
i = Van’t Hoff’s Factor = 32
Kb = ebullioscopic constant = 12

Molality = Î´Tb / iKb
So, Molality = 120 / 384
Molality = 0.3125

Therefore, theÂ molalityÂ isÂ 0.3125.

### Calculating the Van’t Hoff’s Factor when the Boiling Point elevation, Ebullioscopic Constant and Molality are Given

i = Î´Tb / Kb x molality

Where;
i = Van’t Hoff’s Factor
Î´TbÂ = boiling point elevation
KbÂ = ebullioscopic constant
Molality

Let’s solve an example;
Find the van’t hoff’s factor when the boiling point elevation is 240 with a molality of 10 and an ebullioscopic constant of 15.

This implies that;
Î´Tb = boiling point elevation = 240
Kb = ebullioscopic constant = 15
Molality = 10

i = Î´Tb / Kb x molality
i = 240 / 15 x 10
That is, i = 240 / 150
i = 1.6

Therefore, theÂ Van’t Hoff’s FactorÂ isÂ 1.6.

### Calculating the Ebullioscopic Constant when Boiling Point Elevation, Molality and Van’t Hoff’s Factor is Given

kb = Î´Tb / i x molality

Where;
KbÂ = ebullioscopic constant
i = Van’t Hoff’s Factor
Î´TbÂ = boiling point elevation
Molality

Let’s solve an example;
Find the ebullioscopic constant when the boiling point elevation is 180 with a molality of 8 and a van’t hoff’s factor of 15.

This implies that;
Î´Tb = boiling point elevation = 180
i = Van’t Hoff’s Factor = 15
Molality = 8

kb = Î´Tb / i x molality
kb = 180 / 15 x 8
Then, kb = 180 / 120
kb = 1.5

Therefore, theÂ ebullioscopic constantÂ isÂ 1.5.
