Solution: Barbiturates are synthetic drugs used as sedatives and hypnotics. Barbital (MW = 184.2 g/mol) is one of the simplest of these drugs. What is the boiling point of a solution prepared by dissolving 42.5

Problem

Barbiturates are synthetic drugs used as sedatives and hypnotics. Barbital (MW = 184.2 g/mol) is one of the simplest of these drugs. What is the boiling point of a solution prepared by dissolving 42.5 g of barbital in 825 g of acetic acid? [Kb = 3.07°C/m, boiling point of pure acetic acid = 117.9°C]

A) 117.0°C

B) 117.7°C

C) 118.1°C

D) 118.8°C

E) >120°C
