Question

A solution of citric acid C6H8O7 in 50g of accetic acid has a boiling point elevation of 1.76 k If Kb for accetic acid is 3.07 K kg mol -¹ What is the molality of solutions

Answer 1

Answer:

Kb is the molal boiling-point elevation constant for the solvent ... the normal boiling point of acetic acid is 117.9 oC , so the change in boiling point ΔTb is ... mol solute=( molality)(kg solvent).

15.5 g/mol Explanation: We're asked to find the molar mass of the solute, given some known information about boiling-point elevation. To do this, ...
