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

A

90 kg

B

540 kg

C

180 kg

D

270 kg

Text Solution

Verified by Experts

The correct Answer is:
A
`2Al_(2)O_(3)+3Crarr4Al+3CO_(2)`
Production of `4xx27Kg=36kg`
`therefore" Production of 270 kg of Al consumers C of anode"`
`=(36)/(4xx27)xx270=90kg.`
