Depends on a whole lot of things, wind, or lack of it, big time currents, beating into a big steep chop, "schedule", if any, route, meaning fuel availability, that time of year some places may not be open, available space on the boat, may not be a good idea to keep it below.
You didn't say 2 or 4 stroke motor? If 4 stroke you may burn about a half a gallon an hour. With no wind or current your boat may make about 5 knots?
So, it looks like about 10 miles per gallon under ideal conditions, if I have done the math correctly. If it is a 2 stroke it looks close to about 1 gallon an hour.

How much to carry? As much as you can securely stow. For storage purposes, maybe more smaller containers rather than fewer large. Suggest you secure them as best you can.
