A gas bottle contains a mixture of Helium and Oxygen molecules O2 is diatomic. The root mean square' speed, vrms, for the O2 molecules is 482 m/s. Calculate vrms for the Helium molecules (in m/s). DATA: Mass of O2 molecule = 32 x 1.66·10-27 = 5.31·10-26 kg. Mass of He molecule = 4 x 1.66·10-27 = 6.64·10-27 kg. What is the temperature of the gas (in K)?
