The world is a bad place right now tbh.
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)](https://tex.z-dn.net/?f=%5Crm%20%28n%29%20%5Ctimes%20%28delta%5C%3BHrxn%29%20%3D%20%28qrxn%29)
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](https://tex.z-dn.net/?f=%5Crm%20qrxn%20%3D%20%282.8%20mol%29%20%5Ctimes%2825.7%20kJ%2Fmol%29%20%3D%2071.96%20kJ)
Thus, the heat absorbed when 2.8 mol NH₄NO₃ is dissolved in water is 71.96 kJ.
