Homework Statement
The escape velocity of Mars is 5 x 10 ^3 m/s . If the temperature of Mars is 300K , determine whether or not oxygen can exist on the planet . (Molecular mass of oxygen is 32 g/mol)
Homework Equations
The Attempt at a Solution
Using p=1/3 rho <c^2>
p= 1/3 (M/V) <c^2>
pV=1/3 M <c^2> ---1
Then using pV=nRT
pV=2(8.31)(300) since there are 2 moles of oxygen ,
pV=4986
Put this into 1
4986=1/3 (32) <c^2>
<c^2>= 467.44 m/s
Since the mean square speed is lesser than the escape velocity , oxygen exist .
Am i correct ?
