(A) ( K avg ​ ) of one molecule of A = 2 f ​ k T = ( K avg ​ ) of one molecule of B. (B) ( V rms ​ ) A ​ = M A ​ 3 RT ​ ​ = 16 M B ​ 3 RT ​ ​ = 4 1 ​ ( V r m s ​ ) B ​ . (C) P = 3 1 ​ V n M V r m s 2 ​ ​ : P A ​ = 3 V m A ​ ( V r m s ​ ) A 2 ​ ​ , P B ​ = 3 V m B ​ ( V r m s ​ ) B 2 ​ ​ = 3 V 16 m B ​ ( V r m s ​ ) A 2 ​ ​ = 8 P A ​ . (D) N 1 ​ = M A ​ m A ​ ​ N A ​ = 16 M B ​ 2 m B ​ ​ N A ​ = 8 M B ​ m B ​ N A ​ ​ and N 2 ​ = M B ​ m B ​ ​ N A ​ ⇒ N 2 ​ = 8 N 1 ​ .
