F. A student performing an experiment to determine the caloriccontent of a cashew nut collected the following data:

Mass of cashew nut before burning: 0.55 g
After burning 0.05 g
Temperature increase of 200 g of water: 0.7oC.

Calculate the total energy released by the combustion of the cashewnut by using the water temperature increase, the mass of the waterand the specific heat capacity of water.

A student performed this experiment, using a cocktail peanut. Before it was burned, the peanut half weighed 0.353 g. After burning, the residue weighed 0.016 g. The energy released by the combustion increased the temperature of 200.0 ml of water in the calorimeter by 7.2Â° C.

1.) calculate the mass of peanut consumed in the combustion.

2.) Calculate the mass, in kilograms, of water heated.

3.) Calculate the total energy released by the combustion, using the water temperature increase, the water mass, and the specific heat capacity of water.

4.) Calculate the energy released per gram of peanut consumed in the combustion.

A student followed the procedure of this experiment to determine the Caloric content of a Planter's cocktail peanut. The peanut studied had a mass of 0.666g before combustion and 0.058g after combustion. The energy released during combustion caused a 14.1Â°C increase in the temperature of 193.1 mL of water in the calorimeter. a. Calculate the mass (g) of peanut burned b. Calculate the mass (kg) of water present in the calorimeter. c. Calculate the amount of energy released (Cal), from the burning peanut d. Calculate the amount of energy released per gram (Cal/g) of peanut burned
