Question

If compressibility factor of real gas is 1.05 at STP. What is molar volume of real gas?

विकल्प

• 22.40 dm³

• 21.33 dm³

• 23.52 dm³

• 23.05 dm³

Answer 1

23.52 dm³

Explanation:

Compressibility factor (Z) = 1.05 

Under ideal condition, 1 mole of gas accupies

22.4 L volume.

\[Z=\frac{\mathrm{V}_{\mathrm{real}}}{\mathrm{V}_{\mathrm{ideal}}}\]

\[1.05=\frac{\mathrm{V_{real}}}{\mathrm{V_{ideal}}}=\frac{\mathrm{V_{real}}}{22.4\mathrm{dm^{3}}}\]

V_real = 1.05 × 22.4 dm³ = 23.52 dm³
