💡 Solution & Explanation

After electrolysis (knowing the percentage yield 50%) Weight of aluminium deposited, 50 W Z Q 100    1 E W 2F 2 F    1 27 27 2F g 2 3F 3     2 2 3 4Al 3O 2Al O   Amount of aluminium oxide would be formed (assuming 100% yield) = 17 g But it was formed = 8.5 g Required percentage yield = 50%.
