There are 4 oxygen atoms in the formula 2CO2. Each CO2 molecule contains 2 oxygen atoms, so when you have 2 CO2 molecules, you get a total of 4 oxygen atoms.
A CO2 molecule consists of 3 atoms: 1 carbon atom and 2 oxygen atoms.
You multiply the coefficient times the subscripts (number of atoms of each type in the formula) to get the total number of atoms of each element. For example: 2CO2 means 2 carbon atoms and 4 oxygen atoms (No subscript is understood to be 1.) 3C6H12O6 means 18 carbon atoms, 36 hydrogen atoms, 18 oxygen atoms
There are two oxygen atoms in the chemical formula 011.
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).
5, the subscript immediately after the atomic symbol O for oxygen.

There are a total of three oxygen atoms in the formula unit of calcium carbonate, CaCO3.
Nine.
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.
The appropriate rule is that for each element in the formula unit or molecular formula of a compound, the number of atoms of one element is the product of the subscript following the atomic symbol and the coefficient, a normally sized and placed number preceding the formula unit. If either or both of an explicit subscript or coefficient is missing, the number 1 is assumed. Therefore, 2CO2 contains 4 oxygen atoms and 3 H2O contains 3 oxygen atoms, for a total of 7 in the two formulas combined.
To determine the number of atoms of oxygen in the product of a double replacement reaction, you need to know the chemical formula of the product. The number of oxygen atoms will depend on how many oxygen atoms are present in the chemical formula of the product compound. You can count the number of oxygen atoms in the formula of the product to find the total number present.
The compound sodium acetate is C2H3NaO2, so each formula unit has 2 oxygen atoms.
