Answer:
The root mean square velocity of oxygen molecules at 25°C is 1.51m/s.
Explanation:
The root mean square velocity of gaseous molecules is calculated as,
(1)
Where,
=root mean square velocity
R=universal gas constant=0.0821 atm-L/mol-K
T=temperature in kelvin
M=molar mass of gaseous molecules
From the question, we are having,
The gas is oxygen so the molar mass (M)=32
The gas molecules are at temperature(T)=25°C+273K=298K
Now by solving equation (1) we get;
Hence, the root mean square velocity of oxygen molecules at 25°C is 1.51m/s.
