Ans. #3. A. Fat content in Lays chips = 14.0 % of mass of chips
= 14.0 % of 28.0 g
= 3.92 g
Fat content in UTZ chips = 20.6 % of 28.0 g
= 5.768 g
B. Mass of fat = Total mass – (mass of carbohydrates + Mass of protein)
= 28.0 g – (15.0 g + 1.0 g)
= 12.0 g
# Calories from carbohydrates = Mass of carbohydrate x calorific value of carbohydrates
= 15.0 g x (4.0 Cal/ g) = 60.0 Cal
# Calories from protein = Mass of protein x calorific value of protein
= 1.0 g x (4.0 Cal/ g) = 4.0 Cal
# Calories from fats = Mass of fats x calorific value of fats
= 12.0 g x (9.0 Cal/ g) = 108.0 Cal
# Total calories chips = Cal from carbs + Cal from proteins + Cal from fats
= 60.0 Cal + 4.0 Cal + 108.0 Cal
= 172.0 Cal
#C. % Calories from fats = (Calories from fat / Total Calories in chips) x 100
= (108 Cal / 172 Cal) x 100
= 62.79%
