Detailed Solution

Calculating each atom's atomic mass.
Atomic mass of Hydrogen (H) = 1.008.
Sulfur's (S) atomic mass is 32.06.
Oxygen's (O) atomic mass is 16.
Counting the atoms in a substance:
Hydrogen (H) has two atoms.
Sulfur (S) atom number: 1.
Oxygen's (S) atomic number is four.
The molecular weight of H2SO4 is therefore: = 2H + 1S + 4O = 21.008 + 13.206 + 416 = 98.08 gram/mole.
As a result of the computation, we can conclude that the sulfuric acid, or H2SO4, has a molar mass of 98.08 grams per mole.
