Calculating the Molecular Mass of Al2(SO4)3
The molecular mass of a compound is determined by summing the atomic masses of all the atoms present in the molecule. The molecular mass of Al2(SO4)3 can be calculated as follows:
First, identify the atomic masses of the constituent elements:
- Aluminum (Al): 26.98 g/mol
- Sulfur (S): 32.07 g/mol
- Oxygen (O): 16.00 g/mol
Next, count the number of each type of atom in the formula Al2(SO4)3:
- 2 aluminum atoms
- 3 sulfur atoms
- 12 oxygen atoms
Now, calculate the total molecular mass:
Molecular mass of Al2(SO4)3 = (2 × 26.98) + (3 × 32.07) + (12 × 16.00)
Molecular mass of Al2(SO4)3 = 53.96 + 96.21 + 192.00
Molecular mass of Al2(SO4)3 = 342.17 g/mol
Therefore, the molecular mass of Al2(SO4)3 is approximately 342.17 grams per mole.
