how much heat is released when 5.60 moles of NaOH is dissolved in water?

To determine the amount of heat released when 5.60 moles of NaOH is dissolved in water, you need to consider the enthalpy change of the dissolution reaction. The enthalpy change, also known as heat of solution, is the heat absorbed or released during the dissolution process.

To find the answer, you will need to know the standard molar enthalpy of NaOH dissolution in water. This information can be found in reference books or online databases. The standard molar enthalpy of NaOH dissolution is typically given in kilojoules per mole (kJ/mol).

Once you have the standard molar enthalpy value, you can calculate the heat released using the following equation:

Heat released = Moles of NaOH × Enthalpy change per mole

Substituting the given values, the equation becomes:

Heat released = 5.60 moles × Enthalpy change per mole

Remember to use the appropriate sign (+ or -) for the enthalpy change, depending on whether the reaction is exothermic (releasing heat) or endothermic (absorbing heat).
