mass of carbon anode consumed in the production of 270 kg Al

mass of carbon anode consumed in the production of 270 kg Al

 

 

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 (Atomic mass: Al = 27):

2Al2O3 + 3C → 4Al + 3CO2

 

 

 

질량이 주어졌고, 질량을 요구했으므로,

질량비로 계산하면,

( 참고: 질량비로 계산 https://ywpop.tistory.com/5078 )

 

2Al2O3 + 3C → 4Al + 3CO2

 

3C : 4Al = 3(12) : 4(27) = ? kg : 270 kg

 

? = [3(12) × 270] / [4(27)] = 90 kg C

 

 

 

답: 90 kg
