In order to find the actual number of Oxygen atoms in that substance, you must first find the molar mass of that substance by adding the atomic masses of all the atoms which make up that compound. Then, divide the mass of the substance you have by that molar mass. After that, multiply that amount by how many Oxygen atoms are in a molecule of the substance to find how many moles of oxygen you have. Then finally, multiply the number of moles of Oxygen by Avogadro's number (6.022*10^23).
Assuming that the questioner meant to write "permanganate" instead of "promangenate", the answer may be found as follows: The formula of potassium permanganate is KMnO4, showing four atoms of oxygen per formula unit. The formula unit mass of KMnO4 is 158.03; therefore, 17.7 g of potassium permanganate contains [4(17.7)/158.03](Avogadro's Number) or 2.70 X 1023 atoms of oxygen, to the justified number of significant digits.
3KNO3, so 9 oxygen atoms.
In Potassium Sulphate there are two atoms of potassium, one atom of sulphur and four atoms of oxygen so there are 7 atoms and three elements.
Potassium chlorate (KClO3) has 3 oxygen atoms.
Magnesium nitrate is MgNO3 and there are one magnesium atom one nitrogen atom three oxygen atoms no potassium atoms

1 K ( Potassium ) 1 Mn (Manganese) 4 O ( Oxygen ) This is an ionic compound consisting of a +1 potassium cation and a -1 permanganate (polyatomic) anion (MnO4) When this dissociates in water, the K separates from the permanganate, but the permanganate stays together as MnO4
Three potassium oxides are known: - K2O: 2 potassium atoms and 1 oxygen atom - KO2: 1 potassium atoms and 2 oxygen atoms - K2O2: 2 potassium atoms and 2 oxygen atoms
2.4 × 10^23 is the answer
3KNO3, so 9 oxygen atoms.
In Potassium Sulphate there are two atoms of potassium, one atom of sulphur and four atoms of oxygen so there are 7 atoms and three elements.
Potassium chlorate (KClO3) has 3 oxygen atoms.
1:2 --- Three potassium oxides are known: - K2O: 2 potassium atoms and 1 oxygen atom - KO2: 1 potassium atoms and 2 oxygen atoms - K2O2: 2 potassium atoms and 2 oxygen atoms
A compound containing potassium and oxygen atoms would have a formula of K2O, and would be named potassium oxide. This is a binary ionic compound.
If by "pair atoms" you mean molecules, and by potassium and oxygen you mean potassium oxide, then molecules can not be described as metals or nonmentals. Potassium is a metal, while oxygen is nonmetal.
There are 2 potassium atoms, 1 carbon atom and 3 oxygen atoms - K2CO3
Magnesium nitrate is MgNO3 and there are one magnesium atom one nitrogen atom three oxygen atoms no potassium atoms
