The item has 5g net carbs but one serving size is one flatbread and the nutritional facts stated 19g. Per serving. How many actual net carbs are in one serving

We are told that the entire packet contains 8 servings, each serving weighs 42 grams. These 42 grams of a portion of flatbread are equivalent to 19 grams, of these 19 grams 12 are dietary fiber and 2 grams of sugar alcohol.
If we subtract the types of carbs we will have:
19g-12g-2g= 5g.
The net carb means the number of carbohydrates in a food that your body can digest and use for energy.
Dietary fiber and sugar alcohol can not be digested, so we don't count these carbs. Therefore the net carbs will be 5g, as the packet says.
Answer: There are 5g of net carbs per serving
