The answer depends on how much carbonation you want and what temperature you plan to store the beer at.
Most beers like ales, lagers, etc., usually will be carbonated to 2.20 – 2.60 volumes.
If storing the keg at 40-degrees F., you should use 2oz of corn sugar to achieve this carbonation level.
If storing the keg at 55-degrees F., you should use 3oz of corn sugar.
If storing the keg at 70-degrees F., you should use 3.6oz of corn sugar.
There may be a calculator somewhere online that will help you determine the correct amount of sugar to use. I used Beersmith for the above calculations.
(results were rounded up slightly for simplicity)
