A 4.98 g sample of aniline (C6H5NH2, molar mass = 93.13 g/mol) was combusted in a bomb calorimeter with a heat capacity of 4.25 kJ/°C. If the temperature rose from 29.5°C to 69.8°C, determine the value of ΔH°comb for aniline.

  1. delta H = qcal*delta T for a 4.98g sample.
    (delta H/4.98) = delta H in kJ/g. Multiply by molar mass to convert to kJ/mol.
