The molecular formula for sulfuric acid is H2SO4. This shows that each molecule contains exactly 4 oxygen atoms. Therefore, 0.750/4 or 0.1875 moles of sulfuric acid contain 0.750 moles of 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 ======================
The way to work this is out is to first find the mass of one mole of H2SO4 .(98.08 grams). 10 grams is therefore 10/98.08 moles- = 0.102 moles of sulfuric acidEach mole of sulfuric acid contains gram atom of sulfur so we have .102 moles sulfur..if you want the actual count of atoms multiply by avogadros number which is6.0221415 × 1023 (most teachers will accept using 6.022 instead of the longer version)
1.5 moles of Hydrogen. In every mole of H2SO4 (Sulfuric Acid) there are 2 moles of Hydrogen atoms. So, in .75 moles of Sulfuric Acid, there would be 1.5 (double the moles of sulfuric acid) moles of Hydrogen.
0.75 moles of any substance is 0.75(6.02x1023) = 4.52x1023 particles. If those particles are CO2 molecules, and each molecule has 2 oxygen atoms, then it's 2(4.52x1023) = 9.04x1023 oxygen atoms.

2.000 moles of oxygen atoms weigh 32.00 g. 2.000 moles of oxygen molecules, on the other hand, weigh 64.00 g.
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.
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.

There is no direct relationship between grams of oxygenand atoms of oxygen. Use the atomic mass to convert grams to moles and Avogadro's number to convert moles to atoms.Since you are converting from grams O, this goes in the denominator (on the bottom) of the first factor. You want to end up in units of atoms of O, so this goes in the numerator (on the top) of the last factor.g O1.00 mole O6.02E+23 atom O= atoms O16.0 gram O1.00 mole ONote that the units grams oxygen "cancel out" in the first factor and you are left in units of moles. Moles cancel out in the second factor and the final units are atoms oxygen.
224 grams of Oxygen will be in 2 moles of Potassium dichromate.
16 grams of oxygen how many moles is 0,5 moles.
1.5 moles of Hydrogen. In every mole of H2SO4 (Sulfuric Acid) there are 2 moles of Hydrogen atoms. So, in .75 moles of Sulfuric Acid, there would be 1.5 (double the moles of sulfuric acid) moles of Hydrogen.
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.
1 mole of O atoms, or 0.5 moles of o2 molecules.
