6Al2O3
same as
6 * 3
= 18 oxygen atoms
============
One unit of aluminum oxide (Al₂O₃) consists of five atoms in total: two aluminum (Al) atoms and three oxygen (O) atoms. Therefore, the formula indicates that for each molecule of aluminum oxide, there are five atoms combined.
It depends on how many hydrogens are there and how many oxygen atoms there are.
There are 2 oxygen atoms in dioxide
There are 2 atoms and 3 molecules in oxygen.
Heptane has 22 oxygen atoms.
As indicated by the subscript on the atomic symbol for oxygen, there are 3 oxygen atoms.
8. There is 1 hydrogen atom, 3 phosphorus atoms (as indicated by the subscript 3), and 4 oxygen atoms (as indicated by the subscript 4).
The number of atoms is indicated by coefficients.
The chemical formula is MoPO4; the molecule contain four oxygen atoms.
One unit of aluminum oxide (Al₂O₃) consists of five atoms in total: two aluminum (Al) atoms and three oxygen (O) atoms. Therefore, the formula indicates that for each molecule of aluminum oxide, there are five atoms combined.
In the compound 4Fe₃O₂, there are 2 oxygen atoms per formula unit of Fe₃O₂. Since there are 4 formula units (as indicated by the coefficient 4), you multiply 2 oxygen atoms by 4, resulting in a total of 8 oxygen atoms. Therefore, there are 8 oxygen atoms in 4Fe₃O₂.
There are two atoms of oxygen in an oxygen (O2) molecule.
There are 2 oxygen atoms in 1 molecule of oxygen.
It depends on how many hydrogens are there and how many oxygen atoms there are.
In the balanced chemical equation 4 Cr(s) + 3 O2(g) → 2 Cr2O3(g), there are a total of 6 chromium atoms (2 from Cr and 4 from Cr2O3) and 6 oxygen atoms (6 from O2 and 3 from Cr2O3) on the right side of the equation.
There are four oxygen atoms in one molecule of H3PO4.
There are 2 oxygen atoms in dioxide
