Ruby didn't get to know her mom very well, but Yang did, being older than Ruby. Yang didn't get to know her mom either, and has been trying to find out what happened to her mom since she found out that her birth mom is dead. Uh. Nobody ever said that Yang's mother died. Ever. Yang said that her mother left and no one had heard from her since. She said she's trying to find her and find out why she left, not how she died or whatever.

There is absolutely no reason to believe that her mother is dead. In fact, Yang's mother is most likely Raven Branwen, the masked woman from volume 2 episodes 11 and 12.

This is especially since, last year, someone by the username Montyoum (who might actually be the real Monty Oum) edited the Qrow page to say that Qrow's last name is Branwen. Ruby and Yang refer to Qrow as their uncle.
