'Mull Set' . I think you mean 'NULL SET'. This means a set with no elements, or an empty set.
The set contained in another set is termed as a sub-set.
A null set is a set that does not contain any elements, an empty set.
A null set is a set with nothing in it. A set containing a null set is still containing a "null set". Therefore it is right to say that the null set is not the same as a set containing only the null set.

Empty set or null set
empty set is a set because its name indicate as it is the set.
The concept of closure: If A and B are sets the intersection of sets is a set. Then if the intersection of two sets is a set and that set could be empty but still a set. The same for union, a set A union set Null is a set by closure,and is the set A.
The set contained in another set is termed as a sub-set.
A null set is a set that does not contain any elements, an empty set.
A null set is a set with nothing in it. A set containing a null set is still containing a "null set". Therefore it is right to say that the null set is not the same as a set containing only the null set.
That is the definition of a closed set.
