Mixture of chloroform and acetone forms a solution with negative deviation from Raoult's law due to:

Identify the correct statements: A. The molality of 2.5 g of ethanoic acid (Molar mass: 60 g mol-1) in 75 g of benzene solution is 0.556 m. B. The molarity of a solution containing 5 g of NaOH (molar mass: 40 g mol-1) in 450 mL of solution is 0.278 M at 298 K. C. Aquatic species are more comfortable in cold water. D. The solubility of gas increases with decrease in pressure. E. For a binary mixture of A and B, the number of moles of A and B are nA and nB respectively. The mole fraction of B will be χB = nAnA + nB Choose the correct answer from the options given below:

180 g of glucose (C6H12O6) is dissolved in 1 kg of water. At what temperature will water boil at 1.013 bar (Kb for water is 0.52 K kg mol-1)?

Solutions having the same osmotic pressure at a given temperature are called:

According to Raoult's Law, if P0 is the vapour pressure of a pure solvent and P is the vapour pressure of its solution containing a non-volatile solute, where N1 is the mole fraction of the solvent, then:

If P0 and P are the vapour pressures of a solvent and its solution respectively, and N1 and N2 are the mole fractions of the solvent and solute respectively, then according to Raoult's law:

For a 1.0 molal solution containing the non-volatile solute urea, the elevation in boiling point is 2.0 K, while the depression in freezing point in a 3.0 molal solution having the same solvent is 4.0 K. If the ratio Kb/Kf = 1/X, what is the value of X?

A non-volatile solute A weighing 60 g when dissolved in 212 g of the solvent xylene reduces its vapour pressure to 60% of the pure solvent. What is the molar mass of A in g/mol? (Molar mass of xylene = 106 g/mol)
