if you had a solution of an unknown solute dissolved in cyclohexane, and if the freezing point depression of the solution were 9.50 degrees celsius what would be the molality of that solution?

A sample of 3.929 g of polystyrene was dissolved in toluene and diluted to a total volume of 100.8 mL. The osmotic pressure of this solution at 25.0°C was 44.56 torr. What is the molar mass?

2. When 7. 94 g of xylene was added to 132.5 g of cyclohexane, the freezing point of the solution was  -4.9 degrees celsius. What is the molar mass of xylene?

A student dissolves 14. g of sucrose (C,,H,,0,1) in 450. mL of a solvent with a density of 0.85 g/mL. The student notices that the volume of the solvent 22 does not change when the sucrose dissolves in it. Calculate the molarity and molality of the student's solution. Round both of your answers to 2 significant digits. molarity = | x10 molality %3D Continue Submit O 2022 McGraw Hill LLC. All Rights Reserved.

What will be the osmotic pressure exerted by an aqueous solution of 500 mL volume at 25°C if it contains 12.54g dissolved magnesium chloride?

A student dissolves 14. g of aniline (C,H,NH,) in 200. mL of a solvent with a density of 0.90 g/mL. The student notices that the volume of the solvent does not change when the aniline dissolves in it. Calculate the molarity and molality of the student's solution. Round both of your answers to 2 significant digits. molarity x10 molality

Calculate the freezing point of a 0.383 m solution of a nonelectrolyte. The freezing point of the pure solvent is 5.45 °C and Kf is equal to 6.70 °C/m

The boiling point of 6.05 g of a pure solvent is measured to be 48.000 ºC. When 20.00 g of an unknown solute (assume the van 't Hoff factor = 1.0000 for the solute and Kb =  4.85 °C/m for the solvent) is added to the solvent the boiling point is measured to be 55.500  ºC .  What is the molality ( in m) of the solution?(give your answer to two decimal places)
