The osmotic pressure of solution containing 34.2 g of cane sugar (molar mass = 342 g m o l − 1 in 1L of solution at 20 o C is ( G i v e n , R = 0.082 L a t m K - 1 m o l - 1 )

Options

  1. A2.40 atm
  2. B3.6 atm
  3. C24 atm
  4. D0.0024 atm

Correct answer

A. 2.40 atm

Step-by-step solution

π = C R T π = 34.2 342 × 1 L × 0.082 × 293 = 2.40 a t m
