What mass of Mg is produced during electrolysis of molten MgCl ₂ by passing 2 amp current for 482.5 second? ( . Molar mass Mg =24 ~g ~mol ⁻¹ )

Step-by-step solution

aligned & Mg _ ( s ) ²⁺+2 e ⁻ Mg _ ( s ) & Mole ratio = 1 ~mol 2 ~mole ⁻ & W = I ( A ) t ( s ) 96500 ( C / mol e ⁻ ) mole ratio molar mass & W = 2 482.5 96500 ( C / mol e ⁻ ) 1 ~mol 2 ~mol e ⁻ 24 ~g ~mol ⁻¹ & ~W =0.12 ~g aligned
