This question already has an answer here:
I was baffled while using this sentence:
I went into some blog site whose sole purpose. . . .
My question is about whose. Is it correct to use it there?
If you check with a dictionary you would realize:
Note: When whose is used as a pronoun (used without a following noun) , it can only mean "that or those belonging to whom": Whose is this? (It is definitely asking whom this is belonging to) However, when it is used as a possessive adjective, it has the definition "of whom or which".
