Question

Osmotic pressure of one molar solution at 27°C is ______. (R = 0.082)

Options

• 12.1 atm

• 1.21 atm

• 2.46 atm

• 24.6 atm

Answer 1

Osmotic pressure of one molar solution at 27°C is 24.6 atm.

Explanation:

π = MRT (M = Molarity)

= 1 mol dm^-3 × 0.082 dm³ atm K^-1 mol^-1 × 300 K = 24.6 atm
