Question

The nutritional energy content present 78g of lettuce with 1.2g of protein, 2.5g of carbohydrates, and 0.2g of fat is. Round to the nearest 5.

Answer 1

The nutritional energy content of 78g of lettuce is approximately 20 calories.

Step-by-step explanation:

The nutritional energy content of 78g of lettuce can be calculated by multiplying the amount of protein, carbohydrates, and fat by their respective calorie values. Let's use the given values: 1.2g of protein, 2.5g of carbohydrates, and 0.2g of fat. The calorie values for each macronutrient are as follows: protein = 4 calories/g, carbohydrates = 4 calories/g, and fat = 9 calories/g.

Calculating the energy content:

1. Protein: 1.2g × 4 calories/g = 4.8 calories
2. Carbohydrates: 2.5g × 4 calories/g = 10 calories
3. Fat: 0.2g × 9 calories/g = 1.8 calories

Adding up the calories from each macronutrient:

Total energy content = 4.8 calories + 10 calories + 1.8 calories = 16.6 calories

Rounding to the nearest 5, the nutritional energy content of 78g of lettuce is approximately 20 calories.
