This comes up from time to time...but no, 2.2oz corn sugar will not increase ABV by 1%, even in a 1 gallon recipe, nevermind a 5 gallon.
As a general rule, with plenty of room for error, a 5 gallon batch of beer will see a net increase of approximately 1.2% ABV with the addition of one pound of corn sugar. This is assuming the corn sugar measures out to 46 gravity points, which is an estimation in my example.
1 lb corn sugar: ~1.046 for 1 gallon water depending on who you ask/where you look/how you measure.
