1.	When aluminium oxide `(Al_(2)O_(3))` is electrolysed for the production of aluminium metal. For a given quantity of electricty, the number of moles of aluminium obtained if the volume of `O_(2)` gas obtained is 201.6 litre measured at NTP, isA. 9B. 6C. 12D. 4.5
Answer» Correct Answer - C Number of equivalents of oxygen `= (201.6)/(5.6) = 36` (Equivalent volume of oxygen `= 5.6` litre at NTP) `:.` Number of equivalents of `Al = 36` Mass of aluminium `= 36 xx 9 g` Number of moles of aluminium `= (36 xx 9)/(27) = 12`
