A sample of hexane (C6H14) has a mass of 0.580 g. The sample is burned in a bomb calorimeter that has a mass of 1.900 kg and a specific heat of 3.21 J/giK. What amount of heat is produced during the combustion of hexane if the temperature of the calorimeter increases by 4.542 K? Use mc017-1.jpg.

8.46 kJ
16.1 kJ
27.7 kJ
47.8 kJ

The answer is 27.7

According to this equation:
q = M C ΔT
When q= the energy that produced when there is a difference in temperature.
M (g) = amount of the material= 1.900 Kg= 1900 g
ΔT= difference in temperature ( in kelvin or C°)= 4.542 K
C= Specific heat capacity=3.21

∴ q = 1900 * 4.542 * 3.21 = 27701.7 J = 27.7 KJ

Answer:

27.7 kJ
