1. Identify the Elements and Their Atomic Masses
* Nitrogen (N): 14.01 g/mol
* Hydrogen (H): 1.01 g/mol
* Chromium (Cr): 52.00 g/mol
* Oxygen (O): 16.00 g/mol
2. Count the Number of Atoms of Each Element
* Nitrogen (N): 2
* Hydrogen (H): 8
* Chromium (Cr): 1
* Oxygen (O): 4
3. Calculate the Total Mass
(2 x 14.01 g/mol) + (8 x 1.01 g/mol) + (1 x 52.00 g/mol) + (4 x 16.00 g/mol) = 152.04 g/mol
Therefore, the molar mass of ammonium chromate ((NH₄)₂CrO₄) is 152.04 g/mol.
