Whom is the objective case of the pronoun. It is used as a direct object, indirect object or object of the preposition.
If you just look at the sentence you have, you will see whether the pronoun who or whom should be used by the position it is in in the sentence. Another way to decide is to change the question to a statement and substitute he/she or we/they for who and him/her or us/them for whom?
