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

  • Vm > 22.4 L

  • Vm < 22.4 L

  • Vm = 22.4

  • Vm = 44.8 L

Solution

B.

Vm < 22.4 L

compressibility (Z) = PVnRTZ less than unity, thereforePVnRT <1or PV<nRT [At STP, P =1 atm, T = 273K, R =0.0821 L atm K-1]i.e or  1 atm x V < 1 x 0.0821 x 273or V <22.4 litres.
