How much salt do you add to an ounce of water to keep it from freezing?

Just to be clear: adding salt, or anything else, to water will not "keep it from freezing". They just make it freeze at a lower temperature.
The amount of salt you add depends on how much you need the freezing point to drop. If you just need to make sure it doesn't freeze at 0 degrees Celsius, then even a very small amount of salt will work. If you need it to stay liquid at -4 degrees Celsius, you're going to need to add a little over a mole of table salt per kilogram of water; a tenth of an ounce of salt per ounce of water should be more than sufficient.
You can only dissolve about six moles of table salt per kilogram of water, which corresponds to a freezing point of around -23 degrees Celsius. If the temperature is going to be below that, no amount of salt will keep the water from freezing.

How do you delay the freezing of water?
Well, adding Sodium Chloride can do the trick. It depresses the freezing of water therefore it will freeze at a much lower temprature. Actually, salt is used in many occasions to keep things unfrozen-for example, roads in winter...

How much energy is needed to keep one gallon of water from freezing?
None. When water freezes it _releases_ energy (the heat of fusion, 333.55 kj.kg). To keep it from freezing, simply keep the energy constant. If the ambient temperature is below zero C (32 F) the rate of energy loss will depend on the temperature of the air and the thermal resistance (insulation value) of the water's container, and other factors such as wind speed. In those conditions you must replace the energy lost to prevent the water from freezing. However, the energy needed depends on the rate of loss, not on the amount of water.
