Calculate the compressibility factor of 1 mole of a certain real gas if it occupies 0.4 dm ^3 at 300 K and 40 atm. [R = 0.082 atm dm ^3 K ⁻¹ mol ⁻¹ ]

Options

  1. A0.45
  2. B0.65
  3. C0.85
  4. D1.00

Correct answer

B. 0.65

Step-by-step solution

The compressibility factor Z is given by the formula: Z = PV nRT Substituting the given values: Z = 40 0.4 1 0.082 300 Z = 16 24.6 Z 0.65 Answer: 0.65
