Question

How many atoms are present in ${\mathrm{H}}_2{\mathrm{SO}}_4$?

Answer 1

Step 1: Given:

Sulphuric acid ${\mathrm{H}}_2{\mathrm{SO}}_4$ molecule.

Step 2: Calculate the number of atoms in ${\mathrm{H}}_2{\mathrm{SO}}_4$:

From the molecular formula ${\mathrm{H}}_2{\mathrm{SO}}_4$, it contains the following:

• $2$ hydrogen atom $\mathbf{\left(}\mathbf{H}\mathbf{\right)}$

• $1$ sulphur atoms $\mathbf{\left(}\mathbf{S}\mathbf{\right)}$
• $4$ oxygen atoms $\mathbf{\left(}\mathbf{O}\mathbf{\right)}$

Thus,

Total atoms $=2+1+4$ $=7$

Thus, ${\mathrm{H}}_2{\mathrm{SO}}_4$ molecule contains $7$ atoms.
