P = 2 atm
V = unknown
n = 2.0 mol
R = 0.082 atm dm3 K-1 mol-1
T = -133°C = 140 К
Solution:
The Ideal Gas equation can be used: PV = nRT
To find the volume of gas, solve the equation for V:
V = nRT / P
V = (2.0 mol × 0.082 atm dm3 K-1 mol-1 × 140 К) / (2 atm) = 11.48 dm3
V = 11.48 dm3
Answer: 11.48 dm3
