How many atoms are there total in H2SO4

To find the total number of atoms in H2SO4, we need to consider the number of atoms present for each element in the compound.

One molecule of H2SO4 consists of 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms.

The subscript number after each element symbol indicates the number of atoms present in the molecule.

Therefore, in one molecule of H2SO4, there are a total of:
2 hydrogen atoms
1 sulfur atom
4 oxygen atoms

Adding these together, we get:
2 + 1 + 4 = 7

So, there are a total of 7 atoms in one molecule of H2SO4.
