1 carbon 2 oxygen
c=carbon o2=2 oxygens
One Carbon (C) atom and two Oxygen atoms (O). CO2.
There are two carbon atoms in one molecule of CO2.
2 atoms
There are two elements in CO2, carbon and oxygen.
In one molecule of CO2, there is one atom of carbon and two atoms of oxygen.

Carbon dioxide: CO2. The number to the right of the symbol for an element indicates how many atoms of that element are present in single molecule. If there is no number then there is one atom present. Then in the case of carbon dioxide there must be one atom of carbon (C) and two atoms of oxygen (O). Double these to provide the numbers of atoms of the two elements in two molecules: two of carbon, four of oxygen.
Each molecule of carbon dioxide (CO2) contains one carbon atom and two oxygen atoms, totaling three atoms per molecule. Therefore, in 3 molecules of CO2, there are 3 carbon atoms and 6 oxygen atoms, resulting in a total of 9 atoms.
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 0.000831 mole of CO2 will have 0.000831 mole of carbon atoms.
Carbon Dioxide-CO2 To get molecules, we must convert grams to moles and moles to atoms using Avogadro's number. Molar mass of CO2= C:12.0g+O:16.0gx2=44.0g CO2 25.0g CO2 | 1 mol CO2 | 6.02x10 23 molecules CO2 ------------------------------------------------------------------- = 3.42x10 23 molecules CO2 1 | 44.0g CO2 | 1 mol CO2 Now to get the number of oxygen atoms. Since there are 3 atoms in CO2 and 2 of them are oxygen, we will divide by 3 (1.14x10 23) and multiply by 2 (2.28 x10 23) So the number of oxygen atoms in 25.0 grams of CO2 is 2.28x10 23 or 228 000 000 000 000 000 000 000
6 - the 2 in front means 2 molecules of CO2 and the 2 after the O means 2 oxygen atoms per molecule of CO2, so 2 molecules composed of 3 atoms = 6 atoms
