Question

What is the atomicity of sulphuric acid?

• A. $6$
• B. $7$
• C. $3$
• D. $8$

Answer 1

The correct option is B $7$

The atomicity of a molecule is the total number of atoms present in it.​
Sulphuric acid $\left({\text{H}}_2{\text{SO}}_4\right)$ has one sulphur atom, two hydrogen atoms, and four oxygen atoms in it. Hence, a total of $7$ atoms are present.​ Therefore, the atomicity of ${\text{H}}_2{\text{SO}}_4$ is seven.​
