Question

calculate the number of calories in 250 g of spinach having 6.2 g of protein, 9.5 g of carbohydrates, and 1.2 g of fat. use the average caloric content of 4 calories per gram of proteins, 4 calories per gram of carbohydrates, and, and 9 calories per gram of fats and oils. round your answer to the nearest 10. do not include units in your answer.

Explanation:

Step1: Calculate calories from protein

Calories from protein = \(6.2\times4 = 24.8\)

Step2: Calculate calories from carbohydrates

Calories from carbohydrates = \(9.5\times4=38\)

Step3: Calculate calories from fat

Calories from fat = \(1.2\times9 = 10.8\)

Step4: Sum up the calories

Total calories = \(24.8+38 + 10.8=73.6\)

Step5: Round to the nearest 10

\(73.6\approx70\) (rounded to the nearest 10)

Answer:

70
