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

Options

A. `V_(m) gt 22.4` litres
B. `V_(m) lt 22.4` Litres
C. `V_(m) = 22.4` litres
D. `V_(m) = 44.8` litres

Answer

B

Explanation

`Z = (PV)/(nRT)`
As `Z lt 1` (given)
`:. (PV)/(nRT) lt 1 " or "PV lt nRT`
(1 atm) `xx V lt 1`
`mol xx (0.0821 L atm K^(-1) mol^(-1)) xx (273 K)`
`V_(m) lt 0.0821 xx 283 L`
`V_(m) lt 22.4L`
