Al(NO3)3 has 9 atoms of oxygen.
There are 4 oxygen atoms present in a formula unit of potassium sulfate, represented as K2SO4.
In one formula unit of copper sulfate (CuSO4), there are three oxygen atoms.
The chemical formula of barium nitrate is Ba(NO3)2; barium nitrate has six oxygen atoms in the molecule.
Na2SO4
There are 2 oxygen atoms in 1 formula unit of sodium chlorite (NaClO2)
There are a total of three oxygen atoms in the formula unit of calcium carbonate, CaCO3.
The compound sodium acetate is C2H3NaO2, so each formula unit has 2 oxygen atoms.
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).
There are 4 oxygen atoms present in a formula unit of potassium sulfate, represented as K2SO4.
There are three oxygen atoms present in a formula unit of Aluminum Hydroxide (Al(OH)3).
There are a total of 12 oxygen atoms in two calcium carbonate formula units. Each formula unit of calcium carbonate (CaCO3) contains 3 oxygen atoms, so for two formula units, there would be 6 oxygen atoms in each unit, totaling 12 oxygen atoms.
There are no oxygen atoms present in the formula unit of ammonium chloride (NH4Cl). It is composed of nitrogen, hydrogen, and chlorine atoms.
There are three oxygen atoms in each formula unit of lead(II) nitrite, which has the chemical formula Pb(NO2)2.
In one formula unit of copper sulfate (CuSO4), there are three oxygen atoms.
Barium hydroxide (the formula is Ba(OH)2) contain two hydrogen atoms.
A formula unit of sodium acetate contain two oxygen atoms.
The chemical formula of barium nitrate is Ba(NO3)2; barium nitrate has six oxygen atoms in the molecule.
