\(M_X=\dfrac{16+32.3}{1+3}=28\left(\dfrac{g}{mol}\right)\\ M_Y=\dfrac{44+32}{1+1}=38\left(\dfrac{g}{mol}\right)\\ \rightarrow d_{Y/X}=\dfrac{38}{28}=1,36\)
\(M_X=16+32.3=112\left(\dfrac{g}{mol}\right)\\ M_Y=44+32=76\left(\dfrac{g}{mol}\right)\\ \)
dMy/Mx = \(\dfrac{76}{112}=\dfrac{19}{28}\)
`\overline{M_X} = [ 16 . 1 + 32 . 3 ] / [ 3 + 1 ] = 28 ( g // mol)`
`\overline{M_Y} = [ 44 . 1 + 32 . 1 ] / [ 1 + 1 ] = 38 ( g // mol)`
`d_[Y // X] = \overline{M_Y} / \overline{M_X} = 38 / 28 = [19] / 14`
