The molar mass of zinc sulfate (ZnSO4) can be calculated by adding the molar masses of each constituent element in the compound.
First, we break it down: zinc (Zn), sulfur (S), and oxygen (O). The molar masses of these elements are approximately:
- Zn: 65.38 g/mol
- S: 32.07 g/mol
- O: 16.00 g/mol
In a formula unit of ZnSO4, there is 1 atom of zinc, 1 atom of sulfur, and 4 atoms of oxygen. Therefore, we can compute the total molar mass as follows:
- Molar mass of ZnSO4 = (1 × 65.38 g/mol) + (1 × 32.07 g/mol) + (4 × 16.00 g/mol)
- Molar mass of ZnSO4 = 65.38 g/mol + 32.07 g/mol + 64.00 g/mol
- Molar mass of ZnSO4 = 161.45 g/mol
Thus, the molar mass of zinc sulfate (ZnSO4) is approximately 161.45 g/mol.
