Question

Calculate the rms speed of O₂ gas in the mixture of O₂ and N₂ at Temp $\frac{960}{R}$ Kelvin. (R ® Gas constant)

• A. 100 $\frac{m}{s}$
• B. 200 $\frac{m}{s}$
• C. 300 $\frac{m}{s}$
• D. None

Answer 1

Answer: (C)

300 $\frac{m}{s}$

Answer 2

V = $\sqrt{\frac{3RT}{M_{0}}}$ = $\sqrt{\frac{3 \times R \times 960}{32 \times 10^{–3}}}$ = 300 m/s
