Quite a few!
335 moles H2SO4 (4 moles O/1 mole H2SO4)(6.022 X 1023/1 mole O)
= 8.07 X 1026 atoms of oxygen
=======================
1 mole H2SO4 x 4 moles O/mole H2SO4 x 6.02x10^23 atoms of O/mole O = 2.4x10^34 oxygen atoms
17.9325 grams H2SO4 (1 mole H2SO4/98.086 grams(4 moles O/1 mole H2SO4)(6.022 X 1023/1 mole O) = 4.40387 X 1023 atoms of oxygen ======================
Since a single molecule of H2SO4 contains 2 atoms of Hydrogen, 1 of Sulphur and 4 of Oxygen, and one mole contains 6.02 x 1023 molecules, then there are 4 x (6.02 x 1023) atoms of Oxygen, which is approximately equal to 2.408 x 1024 atoms of Oxygen.Answer = 2.408 x 1024
1 mole H2SO4 = 98.078g H2SO4
1 mole of 02 gas has 12,044 281 714.1023 atoms.
1 mole H2SO4 x 4 moles O/mole H2SO4 x 6.02x10^23 atoms of O/mole O = 2.4x10^34 oxygen atoms

We know from looking at the molecular formula that one mole of molecules of H2SO4 contains 2 moles of atoms of hydrogen, 1 mole of atoms of sulfur and 4 moles of atoms of oxygen.
Since a single molecule of H2SO4 contains 2 atoms of Hydrogen, 1 of Sulphur and 4 of Oxygen, and one mole contains 6.02 x 1023 molecules, then there are 4 x (6.02 x 1023) atoms of Oxygen, which is approximately equal to 2.408 x 1024 atoms of Oxygen.Answer = 2.408 x 1024
1 mole H2SO4 = 98.078g H2SO4
1 mole of 02 gas has 12,044 281 714.1023 atoms.
The formula of sulfuric acid is H2SO4, showing that each mole of sulfuric acid contains four mol of oxygen atoms. Therefore 750/4 or 187.5 mol of sulfuric acid will be sufficient.
Just moles against the ratio of hydrogen atoms in compound then against Avogadro's number. Like this 0.09 moles H2SO4 (2 moles H/1 mole H2SO4)(6.022 X 10^23/1 mole H) = 1.1 X 10^23 hydrogen atoms
Since each mole of carbon dioxide molecules contains two moles of oxygen atoms, as indicated by the formula CO2 for carbon dioxide, half a mole of carbon dioxide will have one mole of oxygen atoms.
1 mole of oxygen is 6.022 x 1023 atoms. 1 mole of atoms of any element is always 6.022 x 1023 atoms. 1 mole of anything is 6.022 x 1023 of that thing. For example, 1 mole of cars is 6.022 x 1023 cars.
6.02214076×1023
There are 2 hydrogen atoms and 1 oxygen.
