Question

Calculate the root mean square speed of an oxygen molecule at 288 k in si unit

Answer 1

vrms = [3(8.3145 kg·m2/s2/K·mol)(373 K)/(0.032 kg/mol)]1/2. vrms = [290748 m2/s2]1/2. vrms = 539.2 m/s. Answer: The average or root mean square velocity of the oxygen gas molecules at 0 °C is 461.3 m/s and 539.2 m/s at 100 °C.

Answer 2

vrms = [3(8.3145 kg·m2/s2/K·mol)(373 K)/(0.032 kg/mol)]1/2. vrms = [290748 m2/s2]1/2. vrms = 539.2 m/s. Answer: The average or root mean square velocity of the oxygen gas molecules at 0 °C is 461.3 m/s and 539.2 m/s at 100 °C.J
