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 $50%$ ?

Options:

Answer:

Solution:

$\frac{W _{Ca}}{E _{Ca}} = \frac{W _{Al}}{E _{Al}} \Rightarrow \frac{40}{20} = \frac{W _{Al}}{9} \Rightarrow W_{Al} = 18 kg$ As current efficiency is $50% so, W_{Al} = 9 kg$
