I need to know how to determine the amount of CO2 needed to inflate a life raft without damage by over inflation.

Are you asking theoretically, or literally? Theoretically, use the formula: PV=nRT --> P = pressure, T = temperature, etc.
Literally, just squeeze the raft. If you think it's relatively hard, stop the pumping.

You need to supply more information. Like how much volume does the gas bags in the raft have? How much pressure can the gas bags withstand? What temperature is the gas at? etc.

Just inflate it until it is slightly squishy; that will do fine. But why use CO2? Air is entirely suitable, and it's free.
