5) Based on the experimental freezing point lab data provided below for biphenyl dissolved in, 10.00 grams of an unknown solvent (see page 2), determine the identity of the solvent. Plot the data using excel. Molality values are plotted on the X axis and the freezing point depression values are plotted on the Y axis. What is the slope value (provide equation on the graph) and what is this value related to? Find the identity of the unknown solvent.
