The vapour pressure of water at 20°C is 17.5 mm Hg. If 18 g of glucose (C₆H₁₂O₆ ) is added to 178.2 g of water at 20°C, the vapour pressure of the resulting solution will be

When 25 g of a non-volatile solute is dissolved in 100 g of water, the vapour pressure is lowered by 2.25 × 10^-1 mm. If the vapour pressure of water at 20°C is 17.5 mm, what is the molecular weight of the solute ?

The freezing point of water is depressed by 0.37°C in a 0.01 mol NaCl solution. The freezing point of 0.02 molal solution of urea is depressed by

On adding 1 g arsenic to 80 g benzene, the freezing point of benzene is lowered by 0.19°C. The formula of arsenic is
( K_f = 5.08 K kg mol^-1 )

The osmotic pressure (at 27°C) of an aqueous solution (200 mL) containing 6 g of a protein is 2 × 10^-3 atm. If R = 0.080 L atm mol^-1 K ^-1, the molecular weight of protein is

A solution containing 4 g of polyvinyl chloride polymer in one litre of dioxane was found to have an osmotic pressure of 4.1×10^-4atm at 27°C. The approximate molecular weight of the polymer is
