Based on the formula for sulfuric acid pictured above there are blank molecules and they gave one, two, three as an answers molecules of sulfuric acid in each molecule. There are blank, hydrogen atoms. They have number two, three, four and then blank, sulfur atoms and they gave for that answer one, two, three and blank oxygen atoms and 90 day for that, two, three, four oxygen atoms. This means that there are blank atoms total in this substance and they gave number nine, 21, and seven need help.

The chemical formula for sulfuric acid is \( \text{H}_2\text{SO}_4 \).

From this formula, we can determine the following:

  1. Number of molecules of sulfuric acid: The question seems to ask for the number of molecules in a formula unit of sulfuric acid, which is one. So the answer here is 1 molecule.

  2. Number of hydrogen atoms: The formula \( \text{H}_2\text{SO}_4 \) indicates there are 2 hydrogen atoms.

  3. Number of sulfur atoms: There is 1 sulfur atom in the formula \( \text{H}_2\text{SO}_4 \).

  4. Number of oxygen atoms: There are 4 oxygen atoms in sulfuric acid.

Now, to find the total number of atoms in one molecule of sulfuric acid, we add the number of hydrogen, sulfur, and oxygen atoms together:

  • Hydrogen: 2
  • Sulfur: 1
  • Oxygen: 4

Total = \( 2 + 1 + 4 = 7 \) atoms.

In summary, the filled blanks would be:

  • 1 molecules of sulfuric acid
  • 2 hydrogen atoms
  • 1 sulfur atom
  • 4 oxygen atoms
  • Total of 7 atoms in this substance.
