The tone of a text relates to the author's attitude towards the subject. This can be found in the diction, syntax, setting, and other narrative and thematic details. These same details can tell us about the mood of the text as well, however, as opposed to tone, mood relates to the reader's response to the text. Is the reader made to feel anxious, fearful, excited, or frustrated through the narrative devices employed by the author? These emotional reactions would tell us about the mood of the text.
