Equimolar solution in the same solvent have

58.5 gm of NaCl and 180 gm of glucose were separately dissolved in 1000 ml of water. Identify the correct statement regarding the elevation of boiling point (b.p.) of the resulting solutions.

250 ml of a Sodium carbonate solution contains 2.65 grams of Na₂CO₃. If 10 ml of this solution is diluted to one litre, what is the concentration of the resultant solution? (molecular weight of Na₂CO₃ = 106)

250 ml of a sodium carbonate solution contains 2.65 grams of Na₂CO₃. 10 ml of this solution is added to x ml of water to obtain 0.001 M Na₂CO₃ solution. What is the value of x in ml?
(Molecular weight of Na₂CO₃ = 106)

A solution of acetone in ethanol

25.3 g of sodium carbonate, Na₂CO₃ is dissolved in enough water to make 250 ml of solution. If sodium carbonate dissociates completely, molar concentration of sodium Ion, Na⁺ and carbonate ions, CO2–
3 are respectively (Molar mass of Na₂CO₃ = 106 g mol^–1)

A mixture of ethane and ethene occupies 41 L at 1 atm and 500 K. The mixture reacts completely with 10.3 mole of O₂ to produce CO₂ and H₂O. The mole fractions of ethane and ethene in the mixture are (R = 0.082 L atm K^–1mol^–1) respectively

Which has minimum osmotic pressure?

On mixing, heptanes and octane form an ideal solution. At 373 K, the vapour pressures of the two liquid components (heptanes and octane) are 105 kPa and 45 kPa respectively. Vapour pressure of the solution obtained by mixing 25.0 g of heptanes and 35 g of octane will be (molar mass of heptanes = 100 g mol^–1 and of octane = 114 g mol^–1)

If sodium sulphate is considered to be completely dissociated into cations and anions in aqueous solution, the change in freezing point of water (ΔT_f), when 0.01 mol of sodium sulphate is dissolved in 1 kg of water is (K_f = 1.86 K kg mol^–1)
