Under what pressure will oxygen have the density of 3.2 g/litre at 300 K? For O₂, a = 1.36 atm l² mol⁻² and b = 0.03 mol⁻¹ l.
Options:
Answer:
B
Solution:
Molar volume Vₘ = 32/3.2 = 10 l. Van der Waals: (P + 1.36/100)(10 - 0.03) = 0.0821 × 300 gives P + 0.0136 = 24.63/9.97 = 2.4704, so P = 2.457 ≈ 2.46 atm. Ans: (b)
