The freezing point depression constant (\( K_f \)) for water is \( 1.86 \, {°C·kg/mol} \). If 0.5 moles of a non-volatile solute is dissolved in 1 kg of water, calculate the freezing point depression.
What is the unit of Henry's law constant?
What is the molar mass of solute when 2.3 gram non-volatile solute dissolved in 46 gram benzene at 30°C? (Relative lowering of vapour pressure is 0.06 and molar mass of benzene is 78 gram mol–1)
Calculate the pressure of gas if the solubility of gas in water at 25°C is 6.85 x 10–4 mol.dm–3. (Henry’s law constant is 6.85 x 10–4 mol.dm–3.bar–1)
What is the relation between molar mass of solute and boiling point elevation of solution?
