The temperature at which 4 moles of hydrogen gas would exert a pressure of 256 KPa is 431.4 K

Data obtained from the question

  • Number of mole (n) = 4 moles
  • Volume (V) = 56 L
  • Pressure (P) = 256 KPa = 256 / 101.325 = 2.53 atm
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Temperature (T) =?

How to determine the temperature

The temperature of the gas can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

Divide both side by nR

T = PV / nR

T = (2.53 × 56) / (4 × 0.0821)

T = 431.4 K
