The compressibility of a gas is less than unity at STP, therefore

Options

  1. AV_m 22.4 ~L
  2. BV_m 22.4 ~L
  3. CV_m=22.4 ~L
  4. DV_m=44.8 ~L

Correct answer

B. V_m 22.4 ~L

Step-by-step solution

Since, compressibility (Z)= p V n R T for Z less than unity p V n R T 1 or, p V n R T [At STP, p=1 atm , T=273 ~K , R=0.0821 ~L ~atm ~K ⁻¹ ] i.e. V 1 0.0821 273 Thus, V 22.4 ~L
