Answer:
= -266.24°C
Explanation:
According to ideal gas law;
PV = nRT, where P is pressure, V is the volume, n is the number of moles, R is the ideal gas constant and T is the temperature.
PV = nRT
T = PV/(nR)
= 143 kPa * (1atm/101.325 kPa) * 1.00L / (2.49 mol * 0.08206 Latm/molK)
= 6.91 K
= -266.24°C
