Acertain liquid x has a normal boiling point of 118.90 °c and a boiling point elevation constant kb = 0.82 °c*kg*mol^-1. calculate the boiling point of a solution made of 54.g of potassium bromide (kbr) dissolved in 750. g of x. be sure your answer is rounded to the correct number of significant digits.

The boiling point of solution is

Explanation:

To calculate the elevation in boiling point, we use the equation:

Or,

where,

Boiling point of pure liquid = 118.90°C

i = Vant hoff factor = 2 (For potassium bromide)

= molal boiling point elevation constant = 0.82°C/m

= Given mass of solute (potassium bromide) = 54. g

= Molar mass of solute (potassium bromide) = 119  g/mol

= Mass of solvent (liquid X) = 750. g

Putting values in above equation, we get:

Hence, the boiling point of solution is
