In the title hydrated salt, C(8)H(11)N(2)O(+)·NO(3) (-)·H(2)O, the N-C bond distances [1.349 (2) and 1.413 (2) Å] along with the sum of the angles (359.88°) around the acetamide N atom clearly indicate that the heteroatom has an sp(2) character. The ammonium group is involved in a total of three N-H⋯O hydrogen bonds, two of these are with a water mol-ecule, which forms two O-H⋯O hydrogen bonds. All these hydrogen bonds link the ionic units and the water mol-ecule into infinite planar layers parallel to (100). The remaining two N-H⋯O inter-actions in which the ammoniun group is involved link these layers into an infinite three-dimensional network.
