Why do solids and liquids behave differently?Select the correct response.Because they have different intermolecular forces.Because solids have more particles than liquids.OBecause they vary in particle arrangement.Because they undergo the sanme phase changes. 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 benzenenormally 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 ofthe solute?Select the correct response(s):82.41 g/mol0.59 mO 5.9 m0.90 m81.40 g/mol80.84 g/mol0.95 m84.21 g mol
