If you mean this Al2(CO3)3, then 9 oxygen atoms are represented.
9 atoms
********************
There are 6 oxygen atoms.
There are two oxygen atoms in O2. For ozone which is O3 there would be three.
7 Al2(SO4)3 = 84 oxygen atoms total.
Three

15 atoms.
Four oxygen atoms.
It has 4 oxygen atoms.
There are 2 oxygen atoms in 1 molecule of oxygen.
a. number of atoms = mass / molar mass x avagadros number 21/16x6.02x1023=7.9x1023 atoms b. number of atoms = moles x avagadros number 0.812x6.02x1023=4.89x1023 atoms as there is 1 O atom in each molecule of MgO, there are 4.89x1023 atoms of Oxygen. c. if there are 3.2x1022 molecules and 6 oxygen atoms in each molecule then: (3.2x1022)x6=1.92x1023 Oxygen atoms.
The amounts of the chemical there is preasent. e.g. 3Al2O3 = 3 particles of alaminium oxide. alaminium oxide = Al2O3
15 atoms.
Two oxygen atoms.
There are 2 Oxygen atoms in CaCO2
Four oxygen atoms.
There are 2 oxygen atoms in dioxide
It depends on how many hydrogens are there and how many oxygen atoms there are.
There are 2 atoms and 3 molecules in oxygen.
It has 4 oxygen atoms.
A Molecule of Oxygen contains two atoms
