Question

Weight of O₂ necessary to fill up a cylinder of 0.082 litre capacity at 0˚C and 96 atm pressure would be: (Compressibility factor = 0.96 and gas constant (R) = 0.082 dm³ atm K⁻¹ mol⁻¹)

Vimal Swarnkar · Accepted Answer

(a) 11.72 g. PV = ZnRT → n = PV/(ZRT) = (96 × 0.082)/(0.96 × 0.082 × 273) = 0.3663 mol. Mass = 0.3663 × 32 = 11.72 g → (a).

Answer

(b) 1.172 g

Answer

(c) 117.2 g
