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.

Answer: Molarity of in the original sample was 1.96M
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.
Now put all the given values in the formula of molarity, we get
Thus molarity of in the original sample was 1.96M
