Final answer:
The weight in grams of 1 mole of ammonium sulfate ((NH₄)₂SO₄) is 132.17 g, which is closest to the provided option (d) 132.15 g.
Step-by-step explanation:
To calculate the weight in grams of 1 mole of ammonium sulfate ((NH₄)₂SO₄), we need to find its molar mass by adding the atomic masses of all the atoms in one molecule of ammonium sulfate. Ammonium sulfate is composed of 2 ammonium ions (NH₄+) and 1 sulfate ion (SO₄2-). Using the periodic table, we sum up the atomic weights: for nitrogen (N) 14.01 g/mol, hydrogen (H) 1.01 g/mol, sulfur (S) 32.07 g/mol, and oxygen (O) 16.00 g/mol.
The calculation is as follows:
- (2 x 14.01 g/mol) for nitrogen
- (8 x 1.01 g/mol) for hydrogen
- (1 x 32.07 g/mol) for sulfur
- (4 x 16.00 g/mol) for oxygen
Total molar mass = (2 x 14.01) + (8 x 1.01) + 32.07 + (4 x 16.00) = 28.02 + 8.08 + 32.07 + 64.00 = 132.17 g/mol.
Therefore, the weight in grams of 1 mole of ammonium sulfate is 132.17 g, which is closest to option (d) 132.15 g.
