Molecular Formula: (NH₄)₂C₂O₄
Explanation:
* Ammonium (NH₄): This is the positively charged ion, and since oxalate has a -2 charge, we need two ammonium ions to balance the charge.
* Oxalate (C₂O₄): This is the negatively charged ion.
Molar Mass:
To calculate the molar mass, we add up the atomic masses of all the atoms in the molecule:
* Nitrogen (N): 2 atoms * 14.01 g/mol = 28.02 g/mol
* Hydrogen (H): 8 atoms * 1.01 g/mol = 8.08 g/mol
* Carbon (C): 2 atoms * 12.01 g/mol = 24.02 g/mol
* Oxygen (O): 4 atoms * 16.00 g/mol = 64.00 g/mol
Total Molar Mass: 28.02 + 8.08 + 24.02 + 64.00 = 124.12 g/mol
