Using the formula V = (3RT)/M, where "V" is the velocity, "R" is the ideal gas constant, an "M" the molecular mass (expressed in g/mol), and "T" is the temperature (in Kelvin, because I will use an "R" expressed in Kelvin). I would calculate the data as required
V = sqrt((3RT)/M)
The data of my room is:
R= 8,31447 kg * m^2 * s^-2 * K^-1 * mol^-1
M (O2) = 0,032 kg/mol
T = 77 °F - 25 °C - 298 K
Calculating (avoiding units)
V = sqrt((3*8,31447*298)/0,032)
V= 481,96 m/s
