Question

Under what conditions will a pure sample of an ideal gas not only exhibit a pressure of 1atm but also a concentration of

1 mol / litre. ( R = 0.082 litre atm / mol- 1 K-1)

(A) at S.T.P.

(B) when V = 22.42 L

(C) when T = 12 K

(D) impossible under any condition

Answer 1

(C) when T = 12 K................

Answer 2

T=12K

Explanation:

PV=nRT

P=n/VRT C=n/V

P=CRT

P/CR=T

1×12/1×1=T

12K=T
