Answer:
The root mean square speed of O2 gas molecules is
<u>519.01 m/s</u>
<u></u>
Explanation:
The root mean square velocity :
Molar mass , M
For He = 4 g/mol
For O2 = 2 x 16 = 32 g/mol
O2 = 32/1000 = 0.032 Kg/mol
First calculate the temperature at which the K.E of He is 4310J/mol
K.E of He =
K.E of He = 4310 J/mol
<u>Now , Use Vrms to calculate the velocity of O2</u>
