The normal freezing point of pure benzene is 5.50 °C. What is the freezing point in °C of the resulting solution when 3.85 g of p-dibromobenzene (C6H4Br2, M = 235.90 g/mol) is dissolved in 45.0 mL of benzene. The solute is a non-electrolyte, the freezing point depression constant for benzene is 4.90 °C/m, and the density of liquid benzene is 0.876 g/mL near its freezing point. Give your numerical answer to 2 decimal places; do not include units.
