Computing Molar Mass of Ammonia Step by Step
Molar Mass of Ammonia: Step-by-Step Calculation
1. Identify Element Counts
Read NH3 and list how many atoms of each element are present:
- 1 atom of Nitrogen (N)
- 3 atoms of Hydrogen (H)
2. Determine Atomic Masses
Look up each element mass from the periodic table:
- Nitrogen (N) ~= 14.007 g/mol
- Hydrogen (H) ~= 1.008 g/mol
3. Multiply Atomic Mass by Quantity
Multiply atom count by atomic mass for each element:
- Nitrogen (N): 1 x 14.007 = 14.010 g/mol
- Hydrogen (H): 3 x 1.008 = 3.020 g/mol
4. Sum Total Molar Mass
Add all contributions to get the final molar mass in g/mol.
Molar Mass = (1 x 14.007 + 3 x 1.008)
Molar Mass = 14.010 + 3.020
Molar Mass = 17.030 g/mol
Final rounded value shown on this page: 17.03 g/mol.
