The standard electrode potential for tin

$S{n}^{2+}(aq)+2e^{-}Sn(s)$

is $-0\mathrm{.}138V$ vs$.$ the standard hydrogen electrode $($SHE$).$ What is the value of this standard

electrode potential vs$.$ the following:

$($a$)$ the saturated calomel reference electrode?

$($b$)$ the $A\frac{g}{A}gCl($saturated$)$ reference electrode?

$($c$)$ the $C\frac{u}{C}uS{O}_4($saturated$)$ reference electrode?
