At a certain temperature, molecules of methane gas. ch4 have an average velocity of 0.098 m/s. what is the average velocity of carbon dioxide molecules at this same temperature? detailed explanation !

Average velocity of CO₂ = 0.059 m/s.

Explanation:

Average velocity of a molecule = √(3KbT / molar mass)Kb: Boltzmann constant and T: the temperature (K) At constant temperature; the average velocity of a molecule is inversely proportional to square root of its molar mass (velocity ∝ 1 / √molar mass).

For two molecules (CH₄ & CO₂):

Velocity of CH₄ / Velocity of CO₂ = √(molar mass CO₂ / molar mass CH₄)molar mass of CH₄ = 16.0 g/mol & molar mass of CO₂ = 44.0 g/mol and the average velocity of CH₄ = 0.098 m/s.(0.098 / average velocity of CO₂) = √(44.0 / 16.0) Average velocity of CO₂ = 0.098 / √(44.0 / 16.0) = 0.059 m/s.

The third choice .. (:
