Plots of vapor pressure vs. temperature for a solvent and a solution are shown in the graph below.
If 1.00 mol of solute dissolved in 1.00 kg of solvent raises its boiling point by 2.55°C, determine the approximate concentration of the solution in mol/kg.
The boiling point of the solution obtained by dissolving 1.00 mol of acetic acid (CH3COOH) in 1.00 kg of water (H2O) is 100.7°C. Determine whether X is a weak or strong electrolyte. Explain.
The boiling point of chloroform is 61.17°C and has a boiling elevation constant (Kb) of 3.80°C/m. Calculate the new boiling point if 3.25 moles of CaCl2 (i = 2.2) is added to 6556 mL of chloroform. The density of chloroform is 1.49 g/mL.
