Question

Molecular mass of sulphuric acid (${\text{H}}_2\text{S}{\text{O}}_4$ ) is 132u.

• A. True
• B. False

Answer 1

The correct option is B False

Molecular mass of a substance is the total sum of the atomic masses of the elements present in a molecule.

Molecular mass of sulphuric acid ${\text{H}}_2\text{S}{\text{O}}_4$ is :
$=2\times$ (atomic mass of hydrogen) + (atomic mass of sulphur) $+4\times$ (atomic mass of oxygen) = 2(1) + (32) +4(16) = 98 u.
