The Chemical formula of Ammonium nitrate is ____.

Ammonium nitrate is an ionic salt composed of the ammonium cation (${\text{NH}}_4^{+}$) and the nitrate anion (${\text{NO}}_3^{-}$). Combining these ions in a $1:1$ ratio to balance the charges yields the chemical formula ${\text{NH}}_4{\text{NO}}_3$. It is commonly used in agriculture as a high-nitrogen fertilizer and as a component in explosive mixtures.
