ABSTRACT
The purpose of this lab was to determine the molar mass of biphenyl by using the
freezing point depression method.

INTRODUCTION
In this lab, the task is to find the molar mass of the solute between cyclohexane and
biphenyl.

DATA
Below Table: The masses and freezing points of cyclohexane and cyclohexane biphenyl solution
for trials one and two. (Table 3)

Below Graph: Graph Displaying the Time (mins) Vs. Temperature (C) in Order to Find the
Molecular Weight (g/mol).

Trial 1
Step 1- Finding Delta T (freezing point of
pure cyclohexane):

Step 2- Finding molality:

Step 3- Finding moles of biphenyl solute
(mol):

Step 4- Molar Mass of biphenyl solute:

Step 5- Calcultating percent error:

Trial 2
