Question

cho dx/h2=8,5 và dx/y =0,5 tìm  khối lượng mol cua khi x va khí y

 

Answer 1

\(d_{\dfrac{X}{H_2}}=8,5\\ M_{H_2}=2\\ \Rightarrow M_X=d_{\dfrac{X}{H_2}}.M_{H_2}=8,5.2=17\left(g\right)\)

\(d_{\dfrac{X}{Y}}=0,5\\ \Rightarrow d_{\dfrac{Y}{X}}=2\\ M_X=17\\ \Rightarrow M_Y=d_{\dfrac{Y}{X}}.M_X=2.17=34\left(\dfrac{g}{mol}\right)\)

Answer 2

Ta có: dx/h2 = 8,5

         => Mx = 8,5 . 2 = 17 (g/mol)

           dx/y = 0,5

         => My = \(\dfrac{17}{0,5}\) = 34 (g/mol)

Vậy
