there are three atoms of oxygen in a12o3 but the two in front of it means you have to multiply 3 times 2 wich eguals 6 atoms of oxygen in 2a12o3
There are 3 atoms of oxygen in 2AI203.
I'm not so sure but 11 is probably you answer
look is 12 and u should know that
2
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.
Na2SO4
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
3
There are 2 oxygen atoms in 1 molecule of oxygen.
in the oxygen that we breath there is 2 atoms (O2)
0, there are no oxygen atoms in PROPANE (C3H8 or CH3CH2CH3)
