How much Tylenol?

Our pediatrician had given us a sheet last time but I can’t find it. I called them & waiting for a call back. My baby is 16 pounds how much Tylenol should I give her? She got her 4 month shots today.

Edit: Thank you so much ladies I gave her2.5 & pediatricians office call me and confirm it, they also emailed me the sheet they gave me last visit.
