1. Find the atomic masses of each element:
* N (Nitrogen): 14.01 amu
* H (Hydrogen): 1.01 amu
* Cl (Chlorine): 35.45 amu
2. Multiply the atomic mass of each element by its subscript in the formula:
* N: 14.01 amu * 1 = 14.01 amu
* H: 1.01 amu * 4 = 4.04 amu
* Cl: 35.45 amu * 1 = 35.45 amu
3. Add the results together:
14.01 amu + 4.04 amu + 35.45 amu = 53.50 amu
Therefore, the atomic mass of NH₄Cl is 53.50 amu.
