A 2.9 m solution of methanol (CH3OH) in water has a density of 0.984 g/ml. What are the a) mass percent, b) molarity, and c) mole fraction of methanol in this solution?
If, when you are extracting an aqueous solution with an organic solvent, you are uncertain as to which layer in the separatory funnel is aqueous, how could you quickly settle the issue?
Calculate the boiling point of a solution of 500.0 g of ethylene glycol (C2H6O2) dissolved in 500.0 g of water. Kf = 1.86°C/m and Kb = 0.512°C/m. Use 100°C as the boiling point of water.
