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:
n = 12.18 moles
Explanation:
Given that,
The volume of a canister, V = 1 L
The temperature of the canister, T = 100 K
Pressure, P = 100 atm
We need to find the number of moles of gas. Let there are n number of moles. We know that,
PV = nRT
Where
R is gas constant, R = 0.0821 L*atm/mol*K
Hence, there are 12.18 moles of gas.
