A finite set, with n elements has 2n subsets, including the empty set and itself. For infinite sets the number of subsets is the same order of infinity.
512 subsets
A set with 50 elements has 250 subsets.
A set with N elements has 2N subsets.

Elements belong to subsets: subsets contain elements (from the parent set).
A finite set, with n elements has 2n subsets, including the empty set and itself. For infinite sets the number of subsets is the same order of infinity.
An element doesn't have subsets. Sets can have subsets.
The number of elements. A set with n elements has 2n subsets; for example, a set with 5 elements has 25 = 32 subsets.
512 subsets
A set with 9 elements has 2^9 = 512 subsets.
8 subsets
A set with 50 elements has 250 subsets.
They are collections of some, or all, of the elements of the set. A set with n elements will have 2^n subsets.
A set with n elements has 2n subsets. The number of proper subsets is one less, since 2n includes the set itself.
A finite set with N distinct elements has 2N subsets.
A set with N elements has 2N subsets.
