Question

One gram sample of nh4no3 is decomposed in a bomb calorimeter.

Answer 1

Answer:

Explanation:

heat = mass X specific heat X temp change  

heat = 1g X 1.23 X 6.12 =7.527 kj  

so since molar mass of the sample is 80g/mol , the sample of one gram = 1/80 moles  

since 1/80 moles released 7.52 kj, 1 mole will release 80 X 7.527 kj = 602.2 kj/mol
