A closed vessel contains a mixture of two diatomic gases \( A \) and \( B \). Molar mass of \( A \) is 16 times that of \( B \) and mass of gas \( A \)
\( \mathrm{P} \) contained in the vessel is 2 times that of \( B \). Which of the

W following statements are true?
(A) Average kinetic energy per molecule of \( A \) is equal to that of \( B \)
(B) Root mean square value of translational velocity of \( B \) is four times that of \( A \)
(C) Pressure exerted by \( B \) is eight times of that exerted by \( A \)
(D) Number of molecules of \( B \) in the cylinder is eight times that of \( A \)
