Sure! Here's a sample problem:

What is the enthalpy change of polymerization for the formation of polyethylene with a molar mass of 72.15 g/mol from its monomer, ethylene? Assume that the reaction takes place at constant pressure and temperature of 298 K. The heat of formation of ethylene is -20.4 kJ/mol and the heat of formation of polyethylene is -44.0 kJ/mol.
