1. Identify the elements and their atomic masses:

* Hydrogen (H): 1.008 amu (atomic mass units)

* Sulfur (S): 32.06 amu

* Oxygen (O): 15.999 amu

2. Count the number of atoms of each element:

* H: 2 atoms

* S: 1 atom

* O: 4 atoms

3. Multiply the atomic mass of each element by the number of atoms present:

* H: 1.008 amu/atom * 2 atoms = 2.016 amu

* S: 32.06 amu/atom * 1 atom = 32.06 amu

* O: 15.999 amu/atom * 4 atoms = 63.996 amu

4. Add up the individual atomic masses:

2.016 amu + 32.06 amu + 63.996 amu = 98.072 amu

Therefore, the atomic mass of H₂SO₄ (sulfuric acid) is 98.072 amu.
