25 \times 10^{-3} \text{ m}^3

volume cylinder is filled with 1 mol of

\text{O}_2

gas at room temperature (300 K). The molecular diameter of

\text{O}_2

, and its root mean square speed, are found to be 0.3 nm and 200 m/s, respectively. What is the average collision rate (per second) for an

\text{O}_2

molecule? (1)
