Question

A food contains 28 g carbohydrates, 2.7 g protein, and 0.3 g fats. How many calories does the food provide

Answer 1

There are 4 calories in 1 gram of protein

There are 4 calories in 1 gram of carbohydrates

There are 9 calories in 1 gram of fat

2.7 grams of protein: 2.7 • 4 = 10.8 grams

28 grams of carbohydrates: 28 • 4 = 112 grams

0.3 grams of fat: 0.3 • 9 = 2.7 grams

Add up all 3 results (10.8 + 112 + 2.7) and we get 125.5 grams

Answer: 125.5 grams
