Not at all. The set may be defined in a way that makes this impossible. Consider the following set: "The set of all exceptions to Goldbach's Conjecture". It isn't known whether there areany exceptions. If there aren't, the set is empty. If there are exceptions, the set will have some elements - but we simply don't know. Assuming that one day the Goldbach Conjecture will be proved (or disproved), there will still be other conjectures in Number Theory that can never be proved or disproved, and a similar set can be defined for one of those.
No. If the cardinality of a finite set is N, then that of its power set is 2N. These cannot be equal for any non-negative integer N.
The cardinality of a finite set is the number of elements in the set. The cardinality of infinite sets is infinity but - if you really want to go into it - reflects a measure of the degree of...
It is not possible to answer the question without information about the set B.All that can be said is that if set B has n elements, that is, if the cardinality if B is n, then there are 2n possible subsets of B.
00 is not a set but the number zero written as a 2-digit number. The set {00} has cardinality 1.
Assuming no restrictions on the set, the cardinality of a set, n, is related in this form # of subsets = 2n

Cardinality is simply the number of elements of a given set. You can use the cardinality of a set to determine which elements will go into the subset. Every element in the subset must come from the cardinality of the original set. For example, a set may contain {a,b,c,d} which makes the cardinality 4. You can choose any of those elements to form a subset. Examples of subsets may be {a,c} {a, b, c} etc.

The cardinality of a set is simply the number of elements in the set. If the set is represented by an STL sequence container (such as std::array, std::vector, std::list or std::set), then the container's size() member function will return the cardinality. For example: std::vector<int> set {2,3,5,7,11,13}; size_t cardinality = set.size(); assert (cardinality == 6);
It is impossible. If a set has n elements, the cardinality of its power set [the number of its subsets] is 2n which must be even.
00 is not a set but the number zero written as a 2-digit number. The set {00} has cardinality 1.

Actually, infinity is not a natural number. It is simply a concept of having no upper bound. However, it is possible to have and compare different infinities. For example, we use aleph_0 to represent the cardinality (size) of the set of natural numbers. The cardinality of the set of integers, rational numbers, gaussian integers all have the same cardinality of aleph_0. The set of real numbers has cardinality aleph_1, which is greater than aleph_0. It is possible to create a sequence of increasing infinities (aleph_2, aleph_3, ...), which are called transfinite numbers.
The cardinality of a finite set is the number of elements in the set. The cardinality of infinite sets is infinity but - if you really want to go into it - reflects a measure of the degree of infiniteness. So, for example, the cardinality of {1,2,3,4,5} is 5. The cardinality of integers or of rational numbers is infinity. The cardinality of irrational numbers or of all real numbers is also infinity. So far so good. But just as you thought it all made sense - including the infinite values - I will tell you that the cardinality of integers and rationals is aleph-null while that of irrationals or reals is a bigger infinity - aleph-one.
The cardinality of 15 is equal to the number of elements in the set. Since 15 is only one number, its cardinality is 1.
