To determine the approximate number of electrons in a white tortilla, you need to know its mass and chemical composition. A typical 8-inch white flour tortilla weighs about 51 grams and is primarily composed of carbohydrates, fats, and proteins. [1, 2]
Step 1: Find the mass of the major components
Using the nutrition facts for a standard 51g white tortilla, we can find the approximate mass of the major components:
• Carbohydrates: 25 grams
• Protein: 4 grams
• Fat: 3 grams
• Other ingredients: 19 grams (water, salt, baking powder, etc.)
Step 2: Calculate the number of electrons per gram for each component
Carbohydrates
• Assume the tortilla's carbohydrates are primarily glucose (), a simple sugar.
• The molar mass of glucose is approximately 180 g/mol.
• The number of electrons in one molecule of glucose is found by adding the atomic numbers of its constituent atoms:
• 6 carbon atoms 6 electrons each = 36 electrons
• 12 hydrogen atoms 1 electron each = 12 electrons
• 6 oxygen atoms 8 electrons each = 48 electrons
• Total electrons per glucose molecule: electrons.
• Now, find the number of electrons per gram of glucose.
•
Fat
• Fats are composed of carbon, hydrogen, and oxygen, and have a higher proportion of hydrogen than carbohydrates.
• A representative fat molecule, a triglyceride like tripalmitin (), has a molar mass of about 807 g/mol and 342 electrons.
•
Protein
• The composition of protein varies, but its average electron density is similar to carbohydrates.
• A reasonable estimate for the number of electrons per gram of protein is close to that of glucose, about electrons/g. [3]
Step 3: Calculate the total electrons in the tortilla
Multiply the mass of each component by its approximate number of electrons per gram:
• Carbohydrates: electrons
• Protein: electrons
• Fat: electrons
• Other: The remaining 19g, mostly water, contributes about electrons (1 gram of water contains about electrons).
Total electrons: Summing these values gives an approximation of the total number of electrons. electrons.
The total number of electrons in a typical 51-gram white flour tortilla is approximately .
