Final answer:
The maximum mass of carbohydrate in a 6-oz serving of diet soda that contains less than 1 Calorie per can is approximately 6.9 oz.
Step-by-step explanation:
To find the maximum mass of carbohydrate in a 6-oz serving of diet soda, we need to determine the maximum number of calories that can come from carbohydrates. If the soda contains less than 1 Calorie (1 kcal), the maximum number of calories from carbohydrates would be 1 kcal. Since the average number of calories for carbohydrates is 4.1 kcal/g, we can calculate the maximum mass of carbohydrate by dividing 1 kcal by 4.1 kcal/g, which gives us 0.2439 g. To convert grams to ounces, we multiply by 28.3495 g/oz, giving us approximately 6.9 oz. Therefore, the maximum mass of carbohydrate in a 6-oz serving of diet soda is approximately 6.9 oz.
