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/g times K. What amount of heat is produced during the combustion of hexane if the temperature of the calorimeter increases by 4.542 k?

Answer 1

  The  amount of heat  produced  during  combustion  is  27701.7  j


    calculation
  use   Q =  M CΔT  formula   where
Q(heat) =?
M(mass)=  1.900Kg  in g =  1.900  x1000 = 1900 g
C(specific heat capacity) =  3.21 j/g /k
ΔT =  change in  temperature =  4.542  K

Q  is therefore = 1900 g  x 3.21 j/g/k  x4.542 k = 27701.7 J
