    Using the formula vrms = (the square root of) 3RT/M, R = 8.3143 J/mol K Temperature = 302 K Molar mass F2 = 0.0380 kg / mol Molar mass Cl2 = 0.0709 kg / mol Molar mass Br2 = 0.15981 kg / mol vrms F2 = [ (3) (294 K) (8.3143 J/mol K) / (0.0380 kg/mol) ]^1/2 = 445.23 m/s vrms Cl2 = [ (3) (294 K) (8.3143 J/mol K) / (0.0709 kg/mol) ]^1/2 = 325.95 m/s vrms Br2 = [ (3) (294K) (8.3143 J/mol K) / (0.15981 kg/mol) ]^1/2 = 217.10 m/s
