Root-mean-square. speed of an ideal gas:
v (rms) = sqrt(3RT/M)
where R = 8.31 J K−1·mol−1 is the gas constant, T is the absolute temperature, M the molar mass.
T = 17 + 273 = 290°K
M(chlorine) = 0.071 kg·mol−1
v (rms) = sqrt(3×8.31×290/0.071) = 306.53m/s
v (rms) = sqrt(3RT/M)
where R = 8.31 J K−1·mol−1 is the gas constant, T is the absolute temperature, M the molar mass.
T = 17 + 273 = 290°K
M(chlorine) = 0.071 kg·mol−1
v (rms) = sqrt(3×8.31×290/0.071) = 306.53m/s
