Question

How much heat is absorbed when 2.8 mol nh4no3 is dissolved in water? the heat of solution of nh4no3 is 25.4 kj/mol.

Answer 1

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

What is heat?

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.
