This compound is also used in the production of explosives, primarily for mining and construction purposes. Its dual nature as both a beneficial fertilizer and a potential explosive underscores the importance of understanding its properties, including its molar mass.
Physical and Chemical Properties
- Appearance: White, crystalline solid
- Molecular formula: NH4NO3
- Solubility: Highly soluble in water
- Melting point: 169.6°C
- Density: 1.725 g/cm3
Historical Background
Ammonium nitrate was first synthesized in the 17th century and has since become one of the most significant compounds in agriculture and industry. Its ability to provide an easily accessible form of nitrogen for plants revolutionized farming practices, making it a staple in modern agriculture.
How to Calculate Ammonium Nitrate Molar Mass?
The molar mass of ammonium nitrate is calculated by summing the atomic masses of all the atoms in its molecular formula (NH4NO3). The atomic masses are as follows:
- Nitrogen (N): 14.01 g/mol
- Hydrogen (H): 1.008 g/mol
- Oxygen (O): 16.00 g/mol
Using these values, the calculation is as follows:
- Ammonium ion (NH4): (1 × 14.01) + (4 × 1.008) = 18.048 g/mol
- Nitrate ion (NO3): (1 × 14.01) + (3 × 16.00) = 62.01 g/mol
- Total molar mass: 18.048 + 62.01 = 80.058 g/mol
Thus, the molar mass of ammonium nitrate is approximately 80.058 g/mol.
Why is Accurate Calculation Important?
Accurate molar mass calculations are crucial for a variety of applications, including stoichiometric calculations in chemical reactions, fertilizer formulation, and explosive manufacturing. Small errors in calculation could lead to inefficiencies or even dangerous outcomes, particularly in industrial settings.
