Enthalpy data table
WebThe standard enthalpy of formation (ΔH0f) of a compound is the change in enthalpy that accompanies the formation of 1 mole of a compound from its elements with all substances in their standard states. The table below shows the standard enthalpy of formation, the standard Gibbs free energy of formation, standard entropy and molar heat capacity ... WebQuestion: The value you've determined now, -1150 J/g is the enthalpy of solution for your substance. But without knowing the molecular weight, we can't determine the molar enthalpy of solution. Here's a data table of substances and the molar enthalpy of solution for each. These are expressed in the most common units: kJ/mol.
