Question

What is the mean velocity of one Mole neon gas at a temperature of 400 Kelvin?

• A. 11.533 m/s
• B. 357.578 m/s
• C. 367.79 m/s
• D. 34 m/s

Answer 1

Answer:

A. 11.533 m/s

The formula for mean velocity of a gas is given by the expression √(2RT/M). for one mole of neon gas M is taken as 0.02 kg, temperature as 400 k, R as 8.314 kgm2s-2, so by substituting we get an answer as 11.533 m/s.
