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 molelitre-1?(R = 0.082 litre atmmol-1deg-1)

Options:

Answer:
C
Solution:

The gas has a concentration of 1 mol/L.
This means that V = 1
Number of mol of gas (n) = 1​ mol
P = 1 atm
R = 0.082 L atm mol  K −1
T = ?
SoPV=nRT
SoT=PVnR
=  1 atm × 1 L 1 mol × 0.082 L atm  mol −1   K −1
=  1 0.082  = 12 K
