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.
A 2.11 g sample of ethanol (C2H5OH) is burned in a bomb calorimeter with a heat capacity, C-5.65 kJ/"C. C2H5OH() + 3 O2(g) + 2 CO2(g) + 3 H2O(g) AH'rxn=-1235 kJ If the initial temperature is 25.0°C, what is the final temperature (in "C) of the calorimeter? The molar mass of ethanol is 46.07 g/mol. Remember, in the heat equation, q=m's'AT, heat capacity is equivalent to Cum's, giving Heat capacity is extensive whereas specific heat is intensive. -CAT.

Heat Capacity and Calorimetry
A sample of ethanol, C2H5OH, weighing 2.84 g was burned in an
excess of oxygen in a bomb calorimeter. The temperature of the
calorimeter rose from 25C to 33.73C. If the heat capacity of the
calorimeter and contents is 9.63kJ/C, what is the value of q for
burning 1.00 lol of ethanol at constant volume and 25.00C.
Is q equal to U or H?
