The correct answer is "0.051 N".

Explanation:

Given

Volume,

Normality,

As we know,

⇒

or,

⇒

On putting the values, we get

⇒      

⇒      

⇒      

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
