(Q64) What effect do weak intermolecular interactions between the solute and solvent have on the vapor pressure? O It will be higher than predicted by Raoult's law O It will be lower than predicted by Raoult's law O It will be the same as predicted by Raoult's law O The vapor pressure will be expected to decrease O The vapor pressure of the solution will be higher than that of the pure solvent

(please type answer)

An aqueous antifreeze solution is 44.0% ethylene glycol ( C2 H6O2) by mass. The density of the solution is 1.05 g/cm³. Calculate the molality, molarity, and mole fraction of the ethylene glycol Molality = mol/kg Molarity = mol/L Mole fraction

The boiling point of an aqueous solution is 101.45 Celsius. What is the freezing point?

Decreasing the molarity (mol/L) of an electrolyte in an aqueous solution will have what effect on the solution? The electrical conductivity of the solution will increase with the decreasing molarity. O More than one of these answer choices are true. The boiling point of the solution will increase with the decreasing molarity. The vapor pressure of the solution will increase with the decreasing molarity.

Calculate the total vapor pressure of the following solution: 50.0 ml of 1-butanol (d = 0.810 g/ml; pure vapor pressure of butanol = 17.5 torr) mixed with 50.0 ml of acetone (C3H6O; d = 0.791 g/ml; pure vapor pressure of acetone = 33.2 torr).     25.4     15.7     26.2     28.3     24.5

True or False1.) The phase diagram of a pure solvent shows a lower freezing point compared to solutions2.) The process of freezing only lowers the kinetic energy of solute particles in a solution3.) Ionic solutes have higher van't hoff factor compared to non ionic solutes4.) The formation of intermolecular forces of attraction requires complete dissolution
