On addition of equal number of moles of a non-volatile solute $S$ in equal amount (in $kg$ ) of these solvents, the elevation of boiling point of solvent $X$ is three times that of solvent $Y$. Solute $S$ is known to undergo dimerization in these solvents. If the degree of dimerization is $0.7$ in solvent $Y$, the degree of dimerization in solvent $X$ is. . . . . . .

$Cu^{2+} | Cu = 0.34\, V$
$Ag^+ | Ag = 0.80\, V$ ;
$Zn^{2+} | Zn = -0.76 \,V$
