Problem 79

Given information

The boiling point of solution is .

Step-by-step explanation

The boiling point of pure water is .

The elevation in boiling point is:

The elevation in boiling point is calculated by the formula,

Where,

• is the boiling point elevation constant of water.

• is the molality of solution.

Rearrange the above formula to calculate molality of solution as,

The boiling point elevation constant of water is .

Substitute the value of elevation in boiling point and boiling point elevation constant of water in the above formula.
