How many punches are typically thrown by a boxer in a round?

Obviously this has to do with weightclass etc.. Let's say Pacman. Everyone knows who that is. How many punches does he throw in a round? Would probably put ittsy bittsy Nick Diaz to shame, huh
Maybe boxing doesn't utilize compustrike or the like, but I was hoping someone would know..

Seems He didn't throw nor hit as much as I thought.

Paul Williams throws a shit ton of punches a round though. He's pretty famous for his high pace.
