Question

For electroplating, $1.5$ amp current is passed for $250$ s through $250$ mL of $0.15$ M solution of $M S O_{4}$ . Only $85 %$ of the current was utilized for electrolysis. The molarity of $M S O_{4}$ solution after electrolysis is closets to. [Assume that the volume of the solution remained constant].
