Answer:
Mean square speed of the Oxygen = 130 m/s.
Using the formula,
Mean Square Speed =
Where R is the Universal constant of gas, and T is the temperature, M is the Molar mass of the Oxygen = 32 × 10⁻³ g.
∴ 130 = √[2 × 8.31T/(32 × 10⁻³)]
130 × √(32 × 10⁻³) = √(8.31 × 2T)
∴ √T = 5.7
∴ T = 32.49 K.
