Calculate the amount of POWER you have available from the microphone.
That's ALL you get.  Anything (unpowered) between that and the load 
DECREASES
the available power to your load.

Without knowing the signal level you get from the microphone it's
impossible to say how much gain your amplifier needs to get to 5V
