In a formula unit of lithium phosphate, the chemical formula is Li3PO4. This means there are 4 oxygen atoms present (1 phosphorus atom and 4 oxygen atoms).
4 moles of oxygen atoms are present in 4 moles of H2O
In the reaction 2SO2 + O2 → 2SO3, there are 4 atoms of sulfur (S) present on the left side and 4 atoms of sulfur on the right side. There are 6 atoms of oxygen (O) on the left side and 6 atoms of oxygen on the right side.
In CaSO4 (calcium sulfate), there are a total of 5 atoms present (1 calcium, 1 sulfur, and 4 oxygen). In H2O (water), there are a total of 3 atoms present (2 hydrogen and 1 oxygen). Therefore, in CaSO4 and H2O combined, there are a total of 8 atoms of all kinds present.
There are a total of 24 oxygen atoms present in 6 formulas of molybdenum(IV) phosphate, Mo3(PO4)4. This is calculated by multiplying the number of oxygen atoms in each formula (4) by the number of formulas (6).
There are 4 oxygen atoms present in a formula unit of potassium sulfate, represented as K2SO4.
17 Carbon Atoms, 21 Hydrogen Atoms, 1 Nitrogen Atom and 4 Oxegen Atoms.
A phosphate ion (PO4) contains 4 oxygen atoms, 1 phosphorus atom, and a total of 3 phosphate atoms.
In 4 hydrogen atoms and 2 oxygen atoms, there are a total of 10 atoms (4 hydrogen + 2 oxygen).
In sulfuric acid (H2SO4), there are a total of four oxygen atoms. This is because there are two oxygen atoms in the sulfate (SO4 2-) group and two more in the water molecule formed when sulfuric acid dissociates in solution.
In Na2SO4, there are two oxygen atoms. The total number of atoms in Na2SO4 is two sodium atoms, one sulfur atom, and four oxygen atoms. Therefore, the percentage of oxygen atoms in Na2SO4 is 4 out of 7, which is approximately 57%.
O2 has 2 atoms of oxygen.
