Calculate the Molar Mass of (NH4)2SO4

To calculate the molar mass of ammonium sulfate, (NH₄)₂SO₄, we first need to determine the molar masses of each individual element in the compound and then sum them up based on their quantities in the formula.

The chemical formula consists of:

• 2 ammonium ions (NH₄⁺)
• 1 sulfate ion (SO₄^2-)

Now, let’s look up the molar masses of each element:

• Nitrogen (N): approximately 14.01 g/mol
• Hydrogen (H): approximately 1.01 g/mol
• Sulfur (S): approximately 32.07 g/mol
• Oxygen (O): approximately 16.00 g/mol

Next, we can calculate the molar mass:

• Molar mass of nitrogen in (NH₄)₂: 2 N × 14.01 g/mol = 28.02 g/mol
• Molar mass of hydrogen in (NH₄)₂: 8 H × 1.01 g/mol = 8.08 g/mol
• Molar mass of sulfur in SO₄: 1 S × 32.07 g/mol = 32.07 g/mol
• Molar mass of oxygen in SO₄: 4 O × 16.00 g/mol = 64.00 g/mol

Now, we add these values together:

Molar Mass = 28.02 g/mol (N) + 8.08 g/mol (H) + 32.07 g/mol (S) + 64.00 g/mol (O)

So, Molar Mass = 132.17 g/mol.

Therefore, the molar mass of (NH₄)₂SO₄ is approximately 132.17 g/mol.
