Calculate the i) average speed ii) root mean square speed and iii) most probable speed of 

oxygen molecules at 515 K. (Given  kg mo

To calculate the average speed, root mean square speed, and most probable speed of oxygen molecules at 515 K, we can use the following formulas:

(i) **Average speed**:
\[ \text{Average speed} = \sqrt{\frac{8RT}{\pi M}} \]

(ii) **Root mean square speed (RMS)**:
\[ \text{RMS speed} = \sqrt{\frac{3RT}{M}} \]

(iii) **Most probable speed**:
\[ \text{Most probable speed} = \sqrt{\frac{2RT}{M}} \]

Where:
- \( R \) is the gas constant (8.314 J/(mol·K))
