1. Find the Molar Mass of Each Element
* Nitrogen (N): 14.01 g/mol
* Hydrogen (H): 1.01 g/mol
2. Calculate the Molar Mass of Ammonia (NH₃)
* N: 14.01 g/mol
* H: 1.01 g/mol x 3 = 3.03 g/mol
* Total: 14.01 + 3.03 = 17.04 g/mol
3. Calculate the Percentage Composition of Each Element
* Nitrogen (N): (14.01 g/mol / 17.04 g/mol) x 100% = 82.24%
* Hydrogen (H): (3.03 g/mol / 17.04 g/mol) x 100% = 17.76%
Therefore, the percentage composition of ammonia (NH₃) is:
* Nitrogen (N): 82.24%
* Hydrogen (H): 17.76%
