Answer:
Nutritional calories content present in 100 g of brown bread, rounded to the nearest tens (10)
Item mass nutritional calories
g cal
Carbohydrates 54 220
Protein 11 g 40
Fat 3.3 30
Total (sum) 290
Step-by-step explanation:
According to the USDA (United States Department of Agriculture) the nutrition calories provided by the different groups are:
- Carbohydrates: 4 calories per gram,
- Protein: 4 calories per gram, and
- Fat: 9 calories per gram.
On the other hand, one nutrition calory is equivalent to 1,000 calories as defined by SI.
Based on that, this is the calculation for 100 of brown bread.
Calories content present in 100 g of brown bread:
Item mass nutritional calories SI calories
g cal cal
Carbohydrates 54 54 × 4 = 216 216 × 1,000 = 216,000
Protein 11 g 11 × 4 = 44 44 × 1,000 = 44,000
Fat 3.3 3.3 × 9 = 29.7 29 × 1,000 = 29,700
Total (sum) 289.7 289,700
Rounding to nearest ten (10) of nutrition calories:
Item mass nutritional calories SI calories
g cal cal
Carbohydrates 54 220 220,000
Protein 11 g 40 40,000
Fat 3.3 30 40,000
Total (sum) 290 290,000
