A student follows the procedure for his experiment and burn a peanut. The peanut weighed 0.780 g before combustion and 0.054 g after combustion. The temperature change of an aluminum can be filled with 200 mL of water was 15.3 degree Celsius. (Density of water =1.00g /oC)
a) What is the mass of peanut burned?
b) What is the mass of water in the can?
c) Calculate the amount of energy in Cal, of the peanut:
d) Calculate the amount of energy per gram (Cal/g) of the nut:
e) What cautions would you expect to take in this experiment?
