Abstract
The whole experiment talks about the separation of an aromatic compound, chlorobenzene which is temperature sensitive, from water through the process of steam distillation. The main purpose of this experiment is to determine the composition of the vapor of chlorobenzene and water; to measure the volume of each component in the condensate; and to calculate the molecular mass of the organic compound, chlorobenzene. The vapor pressure of the chlorobenzene and water were 525.8 mmHg and 234.2 mmHg respectively, while the calculated molecular mass for the organic compound, chlorobenzene was 113.70 g with a calculated percent error of 1.01 %.

Introduction
Steam distillation is a known technique that is commonly used for purifying and separating a mixture with two or more different compounds with different boiling points. Steam distillation can be used to separate

While Ma represents the molecular mass of water (18.01 g/mol) and Mb represents the molecular mass of chlorobenzene (112.56 g/mol). In order for the group to get the mass of water, the product of the density of water which is 1.0 g/mL and the volume of the aqueous layer was calculated. As for the mass of the organic compound, chlorobenzene, the product of the density of chlorobenzene which is 1.004 g/mL and the volume of the organic layer was also computed. The table shown below (table 3), represents the computed results and the step by step solution was shown in the
