A sample of 3.05 g of banana was burned in a coffee cup calorimeter filled with 500.0 g of water. the heat released caused the temperature of the water to increase 5.7°c. note: heat capacity, c, of the water is 1.00 cal/g･°c.
calculate the caloric content of the banana in nutritional calories per gram. remember a nutritional calorie (c) is 1 kcal.

The caloric content of the banana in nutritional calories per gram is :

934.4 cal/g

Given data :

mass of banana ( Mb ) = 3.05 g

mass of water ( Mw )= 500 g

change in temperature ( ΔT ) = 5.7°c

Cw =  1.00 cal/g･°c.

Determine the caloric content of the banana

First step : calculate heat released

Qw = Mw* Cw * ΔT

      = 500 * 1 * 5.7

      = 2850 cal

Next step : Calculate the caloric content of the banana

caloric content = Qw / Mb

                         = 2850 cal / 3.05 g

                         = 934.4 cal/g

Hence we can conclude that The caloric content of the banana in nutritional calories per gram is : 934.4 cal/g
