You burn 103.4 mg of phenol in a calorimeter of heat capacity 1,483 J K-1 and the temperature rises by 1.83 oC. Determine the molar heat of combustion for phenol in kJ mol-1. The molar mass of phenol is 94.12 g mol-1
Ccal=deltaH/ deltaT
This is what I did.
n=.1034/94.12
=1.09859E-3mol
deltaH=(1483J/K*274.98K)/1.09859E-3
deltaH=371198.84kJ/mol
What did I do wrong... any help would be appreciated. thanks!
