The effective speed (rms) of the oxygen gas is 293.68 m/s.
<h3></h3><h3>What is Root-mean-square velocity?</h3>Root mean square velocity is the square root of the mean of squares of the velocity of individual gas molecules
<em>where </em>R = universal gas constant
M = molar mass of the gas in kg/mol
T = temperature in Kelvin
According to the ideal gas law,
PV = nRT
RT =
Substitute in the rms velocity formula,
P = 92 kPa, V = 10 L, n = 2 moles and M = 32 x 10⁻³ kg/mol
=293.68 m/s
Thus, the effective speed (rms) of O₂ gas is 293.68 m/s.
