Question
What is the pressure where one mole of a gas at 0oC occupies a volume of 1 liter?
- 760 torr
- 760 mm
- 1000 L
- 22.4 atm
Hint:
P = nRT/V
The correct answer is: 22.4 atm
STP as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 100,000 Pa (1 bar, 14.5 psi, 0.98692 atm).
We know,
PV = nRT 
P = nRT/V
n = 1 mole, T = 273K, V = 1L
P = 22.4 atm
