The molar mass of sulfuric acid (H2SO4) is calculated by adding together the molar masses of all the atoms in the chemical formula.
In sulfuric acid, there are two hydrogen (H) atoms, one sulfur (S) atom, and four oxygen (O) atoms. The molar masses of these elements are approximately:
- Hydrogen (H): 1.01 g/mol
- Sulfur (S): 32.07 g/mol
- Oxygen (O): 16.00 g/mol
Now, we can add them together:
- 2 x Hydrogen: 2 x 1.01 g/mol = 2.02 g/mol
- 1 x Sulfur: 1 x 32.07 g/mol = 32.07 g/mol
- 4 x Oxygen: 4 x 16.00 g/mol = 64.00 g/mol
Adding these values gives:
2.02 g/mol + 32.07 g/mol + 64.00 g/mol = 98.09 g/mol
Therefore, the molar mass of sulfuric acid is approximately 98.09 g/mol.
