Phosphorus pentafluoride is a colorless gas that fumes strongly in air. Phosphorus pentafluoride has a boiling point of -84.6C and has high thermal stability. Dry Phosphorus pentafluoride does not attack glass even at 250c, but a trace of moisture leads to formation of POF and HF( which does attack glass).

a. Calculate the molar mass of Phosphorus pentafluoride.

b. Calculate the root mean square speed of Phosphorus pentafluoride molecules at 85.0C

c. Calculate the kinetic energy per molecule for phosphorus pentafluoride molecules at 85.0C

d. Calculate the kinetic energy per mole for phosphorus pentafluoride at 85.0C
