The mass of carbon anode consumed (giving only carbon dioxide) in the production of 270 kg of aluminium metal from bauxite by Hall process is

A

`180 kg`

B

`270 kg`

C

`540 kg`

D

`90 kg`

Text Solution

Verified by Experts

The correct Answer is:
D
`2Al_(2)O_(3)+underset(3xx12g)(3C)to3CO_(2)+underset(4xx27g)(4Al)`
`4xx27g` of Al are obtained when carbon anode consumed `= 12xx3 g`
