Molar Mass of H2SO4

How to work out the molar mass of H2SO4

1. Count the atoms of each element in H2SO4: 2 H, 1 S and 4 O.
2. Multiply each count by the element's atomic weight: 2 × 1.008 = 2.016; 1 × 32.06 = 32.060; 4 × 15.999 = 63.996.
3. Add the results: 2.016 + 32.060 + 63.996 = 98.072 g/mol.
