Calculate the root-mean-square speed in m s-1 of tungsten hexafluoride at 600K

URMS = sqrt(3RT/M) R= 8.314 (J/mol K) always T is temperature in kelvin and M is molar mass in kilograms
URMS = sqrt (3*8.314*600/M)
Molar mass is equal to WF6 (297.83 g/mol) convert to kilograms by using KHDBDCM.
297.83/1000
.29783 kg/mol=M
URMS= sqrt ({3 * 8.314 * 600}/{.29783})
URMS= 224.159 m/s or ms^-1 [meters per second]
