A factory produces 40 kg of calcium in two hours by electrolysis. How much aluminium can be produced by same current in 2 hours if current efficiency is 50%?

A

22 kg

B

18 kg

C

9 kg

D

27 kg

Text Solution

Verified by Experts

The correct Answer is:
B
`(W_(Ca))/(E_(Ca))=(W_(Al))/(E_(Al))Rightarrow (40)/(20)=(W_(Al))/(9) Rightarrow W_(Al)=18kg `
As current efficiency is 50% so, `W_(Al)=9kg`
