1 oz per gallon, by weight, for a light carbonation.
But remember that if you are doing this with a liquid that has some sugar, either added or naturally, the yeast won't know when to stop or how fast to go- so you may not have it carbonated after two days, or you may have bottle bombs.
You can try first with an unsweetened beverage- say, diet kool aid or crystal light, first- to make sure you know what you're in for!
