Q. A 10.0 L flask contains 64 g of oxygen at 27° C. (Assume $O_2$ gas is behaving ideally). The pressure inside the flask in bar is (Given R = 0.0831 L bar $K^{-1}$ $mol^{-1}$)

A) 4.9
B) 2.5
C) 498.6
D) 49.8
Explanation

[Solution] n = 64/32 = 2 mol; $p = nRT/V = 2 \times 0.0831 \times 300 / 10 = 4.99 \approx 4.9$ bar. Answer (1).
