Question

The average molecular speed in a sample of Kr gas at a certain temperature is 284 m/s. m/s at the same The average molecular

science chemistry

Answer 1

Answer #1

The speed is inversely proportional to square root of molar mass of the gas

Using this, we get: velocity of Oxygen * (molar mass of O₂)^0.5 = velocity of Krypton * (molar mass of Krypton)^0.5

v * (32)^0.5 = 284 * (83.8)^0..5

Solving, v = 459.58 m/s
