In the expression for of a mixture of 2 gases at same temperature, , the molecular weight is
View answer and explanation
Correct option: B
Harmonic mean of molecular weights
Option B is correct because the molecular weight M in the Vrms expression for a gas mixture is the harmonic mean of the individual molecular weights.

Assertion: The pressure exerted by an enclosed ideal gas does not depend on the shape of the container.
Reason: The pressure of an ideal gas depends on the number moles, temperature and volume of the enclosed If is the velocity of sound in air and is the rms velocity, then Four particles have velocities . The root mean square of the particles is (in ) The translational degrees of freedom and rotational degrees of freedom of molecule are: On any planet, the presence of atmosphere implies (= root mean square velocity of molecules and escape velocity) At a given temperature, the pressure of an ideal gas of density is proportional to
