The heat absorbed when 2.8 mol NH₄NO₃  is dissolved in water is 71.96 kJ.

<h3>What is heat?</h3>

Heat is the transportation of energy to or from a thermodynamic system.

By the formula of heat

\rm (n) \times (delta\;Hrxn) = (qrxn)

Where n = moles

Delta Hrxn is molar heat

q = heat

Putting the values in the equation

\rm qrxn = (2.8 mol) \times(25.7 kJ/mol) = 71.96 kJ

Thus, the heat absorbed when 2.8 mol NH₄NO₃  is dissolved in water is 71.96 kJ.
