Consider the combustion of liquid CsHs in oxygen gas to produce carbon dioxide gas and water vapor. In an experiment, 0.1063 g of CsHs is combusted to produce enough heat to raise the temperature of 150.0 g of water by 7.632 °C. This experiment determined the enthalpy of formation of CsHs is 134 kJ/mol. If the literature value for the enthalpy of formation of CsHs is 144 kJ/mol, then what is the magnitude of the percent error for this experiment?

Question
Consider the combustion of liquid CsHs in oxygen gas to produce
carbon dioxide gas and water vapor. In an experiment, 0.1063 g
of CsHs is combusted to produce enough heat to raise the
temperature of 150.0 g of water by 7.632 °C.
This experiment determined the enthalpy of formation of CsHs is
134 kJ/mol. If the literature value for the enthalpy of formation of
CsHs is 144 kJ/mol, then what is the magnitude of the percent
error for this experiment?
