Question

The molecular mass of $H_{2}S{O}_4$ is :

• A. 32
• B. 64
• C. 50
• D. 98

Answer 1

The correct option is D

98

Molecular mass is the mass of a molecule. It is calculated as the sum of the mass of each constituent atom multiplied by the number of atoms of that element in the molecular formula. The molecular weight of $H_{2}S{O}_4$ is:

2 $\times$ 1 + 32 + 4 $\times$ 16

= 2+32+64

= 98 g/mol.
