Solution:
Ideal gas equation is given as:
[tex]PV = nRt[/tex]
Where,
P = pressure
V = volume
n = amount of substance
R = ideal gas constant
T = temperature
From given,
V = 120 liters
n = 5 moles
[tex]R = 8.314\ \frac{Lkpa}{mol\ K}[/tex]
P = 5.4 kPa
T = ?
Therefore,
[tex]5.4 \times 120 = 5 \times 8.314 \times T\\\\648 = 41.57 \times T\\\\T = 15.58\ kelvin[/tex]
Thus the temperature is 15.58 kelvin
