A closed vessel contains a mixture of two diatomic gases A and B. The molar mass of A is 16 times that of B and the mass of gas A in the vessel is 2 times that of B. Which of the following statements

Question

A closed vessel contains a mixture of two diatomic gases A and B. The molar mass of A is 16 times that of B and the mass of gas A in the vessel is 2 times that of B. Which of the following statements are true?

Same T gives equal average kinetic energy (A). v ∝ M ​ 1 ​ gives v B ​ = 4 v A ​ (B). The moles ratio is n A ​ n B ​ ​ = M A ​ m A ​ ​ M B ​ m B ​ ​ ​ = 2 1 ​ × 16 = 8 , so there are 8 times as many molecules of B (D), and at the same V and T the partial pressure is 8 times too (C). All four.
