express your answer to one significant figure and include the appropriate units.

100 cal

Explanation:

Given data:

Mass of carbohydrate = 19 g

Mass of protein = 1 g

Mass of fats = 4 g

Solution:

The average calories content of

Protein 4 cal/g

Carbohydrate 4 cal/g

Fat 9 cal/g

Then,

1 g protein × 4 cal/g =  4 cal

4 g fat × 9 cal/g = 36 cal

19 g carb. × 4 cal/g = 76 cal

               Total calories = 116 cal  

Round to one significant figure = 100 cal
