= 1.38 moles
Explanation;Using the equation;
PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.
P= 331 000Pa or 3.267 atm T= 197.4 +273 = 470.4, V = 16.3 L
Therefore;
n = PV/RT
= (3.267 × 16.3)/(470.4 × 0.08206)
= 1.3796 moles
≈ 1.38 moles
