question attached below.

Step-by-step explanation:

From the graph prepared in question 3, determine the freezing point of pure benzophenone. °C Freezing Point of Benzophenone and Cyclohexanone Solution A. Solution 1 1. Volume of cyclohexanone mL 2. Calculate the mass of this volume of cyclohexanone using its density d 0 48 g/ml I m L 3

x/2-5=20

x=20(2-5)

x=40-100

x= -60
