Question

The amount of $Na$ produced by the passage of $2$ moles of electrons through the fused $NaCl$ is ______ g.

• A. $23$
• B. $46$
• C. $11.5$
• D. $34.5$

Answer 1

The correct option is B $46$

Reaction is $N{a}^{+}+e^{-}\to Na$
$1mole$ of electron produces $1moleNa$ or $23g$ of $Na$
Thus $2mole$ electrons will produce $2\times 23=46g$ of $Na$.
