Question

when you discuss calories in food you are talking about kilocalories (Kcal) which is the amount of heat necessary to raise 1000 mL of water by 1 degree Celsius which is approximately 4.18 kJ. compare the number of Kilocalories in one gram of tomatoes to the number of Kilocalories in one gram of corn chips

Answer 1

100 g of corn chips has 17.69 calories

1 g of corn chips has 17.69/100 or 0.1769 calories

Therefore, 1 g of tomatoes has 0.1769 x 10⁻³ kilocalories

100 g of corn chips has 518 calories

1 g of corn chips has 518/100 or 5.18 calories

Therefore, 1 g of corn chips has 5.18 x 10⁻³ kilocalories
