Question
A closed vessel contains a mixture of two diatomic gases A and B. molear mass of A is 16 time that of B and mass of gas A contained in the vessel is 2 times of B. which of the following statements are true ?
Options
A.Average kinetic energy per molecule of A is equal to that of B
B.Root mean square value of translation velocity of B four times of A
C.Pressure exerted by B is eight time of that exerted A
D.Number of molecules of B in the in the cylinder is eight times that of A
Solution
Average KE per molecule in A& B = 
(vrms)A =
; (vrms)B = 
⇒
No. of mole of A =
No. of mole of B =
= 8nA
Pressure exerted by a gas in the vessel depends on the number of molecules present inside.
(vrms)A =
; (vrms)B = ⇒
No. of mole of A =
No. of mole of B =
= 8nAPressure exerted by a gas in the vessel depends on the number of molecules present inside.
