The heat absorbed when 2.8 mol NH₄NO₃ is dissolved in water is 71.96 kJ.
Heat is the transportation of energy to or from a thermodynamic system.
By the formula of heat
[tex]\rm (n) \times (delta\;Hrxn) = (qrxn)[/tex]
Where n = moles
Delta Hrxn is molar heat
q = heat
Putting the values in the equation
[tex]\rm qrxn = (2.8 mol) \times(25.7 kJ/mol) = 71.96 kJ[/tex]
Thus, the heat absorbed when 2.8 mol NH₄NO₃ is dissolved in water is 71.96 kJ.
