How many carbohydrates are burned in a workout?

The answer lies in your question itself: "How many carbohydrates are burned in a workout?" The key Word here is carbohydrates. Regardless of the intensity or mildness of a workout, regardless of the food consumed or not consumed, regardless of the activity participated in, you will never, ever, burn carbohydrates through a work out. Why? Because carbohydrates aren't burned through workouts! You're measure of a workout is done by burning calories, not carbohydrates. Calories are the unit of energy that we should focus on here. Carbohydrates carry 4 calories per gram as does protein, however, for each gram of fat in a particular food, there is 9 calories, almost double the amount! This explains the reasons for such shun when it comes to talk about "fat" in foods... however, good fats, like olive oil and the grams stemming from nut assortments, is not only good for you but beneficial. Good luck in your workout endeavors! :)
