Answer:
98.09g/mol
Explanation:
the molar mass of any compound is derived by the multiplying the individual atomic masses of each of the elements present in the compound by the number of atoms each element has and then adding each of the values together
for H₂SO₄ (sulphuric acid)
elements present are hydrogen, sulphur and oxygen
atomic mass of hydrogen = 1.00784
atomic mass of sulphur =32.065
atomic mass of oxygen = 15.999
the acid contains 2 atoms of hydrogen, one atom of sulphur and 4 atoms of oxygen
∴molar mass of H₂SO₄ = (2 × atomic mass of hydrogen) + atomic mass of sulphur + (4 × atomic mass of oxygen)
= (2 × 1.00784) + 32.065 + (4 × 15.999)
= 2.01568 + 32.065 + 63.996
= 98.09g/mol
