a) If you mean per molecule, it's 3/2*kT, where k = Boltzmann's Constant, so that's 3/2(1.381*10

^{-23})(354) =**7.333*10**For a mole of gas, multiply by Avogadro's Number, 6.022*10^{-21 }J.^{23}=**4416 J/mol**or 4.416 kJ/molb) V

_{rms }= √(3RT/M) R = Gas Constant; M = molar mass in kg. So V = √(3*8.314*354/0.02018) =**661.5 m/s**c) Since T is under a square root symbol, you would have to multiply it by 9 (because √9 = 3), so that's 354*9 =

**3186 K**
