Under what conditions will a pure sample of an ideal gas not only exhibit a pressure of `1 atm` but also a concentration of `1 mol litre^(-1)`
`[R= 0.082` iltre atm `mol^(-1)K^(-1)]`

Options

A. at `STP`
B. when `V=22.42L`
C. when `T= 12 K`
D. impossible under any condition

Answer

C

Explanation

`P=CRT, T=(P)/(RC)=(1xx12)/(1xx1)=12K`
