A 6.55 g sample of aniline (C₆H₅NH₂), molar mass = 93.13 g/mol) was combusted in a bomb calorimeter with a heat capacity of 14.25 kJ/°C. If the initial temperature was 32.9°C, use the information below to determine the value of the final temperature of the calorimeter.
The heat of combustion in bomb calorimeter problems isgenerally calculated by the following formula H = -C T
Bromine has atomic number 35 which means there are 35 protons and 44 neutrons to give a total of 79 nucleons. the fact that it's a positive ion means that it has lost an electron; so there'll be 34 electrons.
Moles of co₂ = 2.35/44 = 0.0534 mole.from ideal gas equation pv=nrt, t = 18+273k = 291 kelvin.∴px5 = 0.0534x0.0821x291∴p = 0.0534x0.0821x291/5 = 0.2551 atm.now, 1 atm = 760 mm of hg ∴ 0.02551 atm = 0.02551 x 760 = 19.38 mm of hg
