A2.5 g sample of french fries is placed in a calorimeter with 500.0 g of water at an initial temperature of 21 °c. after combustion of the french fries, the water has a temperature of 48 °c. what is the caloric value (kcal/g) of the french fries?

Q=m°CΔT
=(500g) x (1 cal/g.°C) x (48°C-21°C) = 13500 cal
13500 cal / 1000 = 13.5 kcal

"What is the caloric value (kcal/g) of the french fries?"
13.5 kcal/ 2.5 g = 5.4 kcal/g
