What is the molecular weight of sulfuric acid?

The total sum of the masses of the atoms or elements present in the molecule is termed as molecular weight.

To calculate the molecular weight of a compound we need to add the mass of individual atoms present in the molecule.

Molar mass of H2SO4

Look for the atomic masses of hydrogen, sulfur and oxygen.

H = 1.008

S = 32.06

O = 16

Therefore, the molar mass of H2SO4 is

=2(1.008) + 32.06 + 4(16)

=98.08 g/mol

Answer

Hence, molecular weight of H2SO4 is 98.08 g/mol.
