I don't know if this is the official thread for Final Empire or if these mistakes have been corrected, but...
Page 298 (paperback) - chapter 17 - the first sentence after the first break: "Later that evening, Vin still couldn't believe how eager she was to go the ball." --> should be "...was to go to the ball."
Page 299 (paperback) - chapter 17 - "Noblewomen didn't get annoyed when they couldn't to go out stalking at night." --> there's an extra word there.
Hope this helps :-)
