Question

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?

A. 8.46 kJ
B. 16.1 kJ
C. 27.7 kJ
D. 47.8 kJ

Answer 1

C) 27.7 kJ

Step-by-step explanation:

Answer 2

27.7 KJ

Step-by-step explanation:

Q= mC dT

m= 1900 g+0.580 g= 1900.58 g

Q= (1900.58 g * 3.21 KJ/ gK* 4.542 K)

Q=27710 J= 27.7 KJ
