A student dissolved 20.0g of an unknown nonelectrolyte solute in 250 mL of benzene, C,H. The resulting solution had a boiling point of 82.5 C, whereas benzene
normally boils at 80.1°C. Suppose the boiling point elevation constant of benzene is 2.53"C/m and has a density of 1g/mL. What are the molality and the molar mass of
the solute?
Select the correct response(s):
82.41 g/mol
0.59 m
O 5.9 m
0.90 m
81.40 g/mol
80.84 g/mol
0.95 m
84.21 g mol
