Osmotic pressure exerted by a solution prepared by dissolving one gram mole of a solute in 22.4 litres of a solvent at 0°C will be _______________ atmosphere?

Question

Accepted Answer

1. One gram mole of an ideal gas occupies 22.4 liters at STP (0°C and 1 atm). According to van't Hoff's law for dilute solutions, the osmotic pressure equals the gas pressure exerted by the same amount of substance in the same volume at that temperature.
