Question

Calculate the osmotic pressure of 0.01 M solution of cane sugar at 27°C. (R = 0.0821 L atm K⁻¹ mol⁻¹)

Answer 1

Given: Molarity (C) = 0.01 mol/L

Temperature (T) = 27°C = 300 K

Gas constant (R) = 0.0821 L atm K⁻¹ mol⁻¹

π = CRT

π = 0.01 × 0.0821 × 300

π = 0.2463 atm

∴ The osmotic pressure of the solution is 0.246 atm.
