Which of the following relationship is correct for a nonvolatile solute? (I-III) I) The vapor pressure of a solution is greater than the vapor pressure of the pure solvent II) The boiling point of a solution is greater than the boiling point of the pure solvent. III) The freezing point of the solution is greater than the freezing point of the pure solvent. THE CORRECT ANSWER IS : ONE STATEMENT IS CORRECT. I don’t know which one it is, Please help!!!

To a beaker containing water, you add so much table sugar that it doesn't fully dissolve in the water. Which of the following is true about the contents of the beaker? O the mixture can be separated back into sugar and water most easily by differences in chemical properties of the sugar and water the mixture is homogeneous the mixture is a colloid the mixture will exhibit the Tyndall effect

Which of the following 0.250m solutions has the greatest freezing point depression? - KCL -CH2O -CaCl2

Solve it with reason

Hi, sorry about the unrelated Question I sent previously with the first one. It was related to a different question.  a) Calculate and enter the freezing point depression of a solution of 52.4 g ethylene glycol (C2H6O2) in 364 g H2O.Kf for H2O is 1.86 °C kg/mol.  b) A solution which contains 77.5 g of an unknown molecular compound in 342 g of water freezes at -5.18°C.What is the molar mass of the unknown? * I got 4.31 degrees celsius for A which was correct. I just need help with B.
