There is an argument whether Adam Harishon burried her or Chanoch burried her which indicates she outlived Adam as he did not burry her. Her age at her passing is not known. google your OP.
I’m not sure if it says anywhere how long chava lived. but if it doesn’t, that means that its not important to know. the Torah is not a story book Chas Veshalom. the Torah – meaning every detail that is in the torah – is to teach us something. What is not important for us to know does not appear in the Torah.
