The percentage of each of the nutrients in the deluxe fast food hamburger is:
- percentage composition of carbs = 40.5 %
- percentage composition of fats = 35.1 %
- percentage composition of proteins = 24.3 %
<h3>What is the percentage composition of the carbs, fats, and protein in deluxe fast food hamburger?</h3>
The percentage composition of the carbs, fats, and protein in deluxe fast food hamburger is obtained from the masses of the nutrients present in the hamburger as follows:
- percentage composition of nutrient = (mass/total mass of nutrients) * 100 %
mass of carbs = 45 g
mass of fats = 39 g
mass of proteins = 27 g
Total mass of nutrients = 111 g
percentage composition of carbs = 45/111 * 100%
