Question

calculate the molecular mass of h2so4

Answer 1

hey dear
here is your answer

molecular mass of H2SO4 =
2×molar mass of Hydrogen + molar mass of Sulphur + 4×molar mass of Oxygen
(2×1)+(32)+(4×16)
2+32+64
98

so molecular mass of H2SO4 or sulphuric acid is 98.

hope it helps
have a good day ☺

Answer 2

Given :

H₂SO₄

To Find :

Molecular Mass of H₂SO₄

Solution :

We know, The molecular mass of a compound is the sum of the atomic masses of the atoms that constitutes the compound.

Atomic mass of H = 1 u

Atomic mass of S = 32 u

Atomic mass of O = 16 u

Molecular mass of H₂SO₄ = 2×1 + 32 + 4×16

                                           = 98 gm/mol

Therefore, the Molecular mass of H₂SO₄ is 98 gm/mol
