A 9.8 g sample of ethanol (C2H5OH) is burned in a bomb calorimeter with a heat capacity, C = 5.65 kJ/°C.
C2H5OH(l) + 3 O2(g) → 2 CO2(g) + 3 H2O(g) ΔH°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*∆T, heat capacity is equivalent to C= m*s, giving q = C* ∆T.
Heat capacity is extensive whereas specific heat is intensive.
