Answer:
118.75°C is the boiling point of a solution.
Explanation:
Mass of the solute that is barbiturates = 42.5 g
Molar mass of a solute = 184.2 g/mol
Moles of solute = 
Mass of the solvent that acetic acid = 825 g = 0.825 kg
Molality of the solution (m):
Elevation in boiling point is given as:
i = 1 (organic compound)
= Boiling temperature of solution.
T = boiling temperature of solvent that is acetic acid=117.9°C
118.75°C is the boiling point of a solution.
