WebAug 25, 2024 · We have used this simple model to predict such properties as freezing points, melting points, vapor pressure, and osmotic pressure. If this model were perfectly correct, we would expect the freezing point depression of a 0.10 m solution of sodium chloride, with 2 mol of ions per mole of \(NaCl\) in solution, to be exactly twice that of a … WebCalculate the boiling point and the freezing point of these solutions at 760 mmHg. 20.0 g citric acid, C6H8O7, in 100.0 g water 3.00 g CH3I in 20.0 g benzene (Kb benzene = 2.53 °C kg/mol; benzene = –5.10 °C kg/mol)
WebThe Ca(NO 3) 2 solute separates into three ions—one Ca 2 + and two NO 3 − —when it dissolves, so its osmolarity is as follows: osmol [Ca(NO 3) 2] = 0.30 M × 3 = 0.90 osmol. The osmolarity of the Ca(NO 3) 2 solution is lower than that of the NaCl solution, so water will transfer through the membrane from the Ca(NO 3) 2 solution to the ...
