How many moles of electrons are required to electroplate a $0.5$ mole of silver from a nitrate solution?

The correct option is C $0.5$
$A{g}^{+}+e^{-}\to Ag$
The electroplatingof 1 mole of silver from 1 mole of silver nitrate requires 1 mole of electrons.
The electroplatingof $0.5$ mole of silver from $0.5$ mole of silver nitrate will requires $0.5$ mole of electrons.
