Question

A 12.8 g sample of ethanol (C₂H5OH) is burned in a bomb calorimeter with a heat capacity of 5.65 kJ/°C. Using the information below, determine the final temperature of the calorimeter if the initial temperature is 25.0°C. The molar mass of ethanol is 46.07 g/mol.
C₂H5OH(l) + 3 O2(g) → 2 CO₂(g) + 3 H₂O(g) ΔH°rxn = -1235 kJ
85.7°C
53.4°C
74.2°C
111°C
28.1°C
