Question

calculate the root mean square speed and the average kinetic energy of a molecule of Oxygen gas at a temperature of 300k​

Answer 1

$Solution =>\\\\V_{rms} = \sqrt\frac{3RT}{m_{o} } \\\\=> \sqrt\frac{3X(8.3JK^{-1}mol^{-1}X300K)) }{32gmol^{-1} }\\\\=> \sqrt\frac{3X8.3X300 ms^{-1} }{0.032} \\\\= 483ms^{-1}$
