To calculate the molar mass of sulfuric acid (H2SO4), we need to add the atomic masses of two hydrogen atoms, one sulfur atom, and four oxygen atoms.

Atomic mass of hydrogen (H) = 1.008 grams per mole (g/mol)

Atomic mass of sulfur (S) = 32.066 g/mol

Atomic mass of oxygen (O) = 16.000 g/mol

So, the molar mass of H2SO4 = (2 x 1.008 g/mol) + (1 x 32.066 g/mol) + (4 x 16.000 g/mol)

= 2.016 g/mol + 32.066 g/mol + 64.000 g/mol

= 98.082 g/mol

Therefore, one mole of sulfuric acid (H2SO4) would have a mass of 98.082 grams.
