pH = 4.97
Explanation:
Ammonium nitrate is the salt of a weak base and a strong acid so we would expect it to be slightly acidic due to salt hydrolysis:
The position of equilibrium lies well to the left such that
From an ICE table we get this expression which can be used to find the pH of a weak acid:
