3 atoms. 1 carbon atom and 2 oxygen atoms.
Twelve. Glucose is C6H12O6, so two molecules of glucose would give you: 12 carbon atoms 24 hydrogen atoms 12 oxygen atoms The 12 molecules of oxygen would give 24 oxygen atoms, for 48 total atoms of oxygen. So...each carbon atom would take two oxygen atoms to give 12 molecules of carbon dioxide, and each remaining oxygen atom would take two hydrogen atoms to give 12 molecules of water.
12************************2nd Opinion: You probably mean "in one molecule of carbon dioxide", CO2, andthe answer would be 3 atoms. One carbon atom and two oxygen atoms.
The compounds resulting from the total burning of hydrocarbons are carbon dioxide and water.
5 molecules of carbon dioxide will contain 5 carbon atoms (1 per molecule) and no hydrogen atoms as carbon dioxide contains only carbon and oxygen. The 5 molecules will contain a total of 10 oxygen atoms (2 per molecule).
2 CO2 means there are two molecules of carbon dioxide. In one molecule of CO2 there is 1 carbon atom, and 2 oxygen atoms. So three atoms total. Therefore, in 2 molecules (each with 3 atoms) there are 6 atoms total. The molecules are made of atoms of carbon and oxygen. The atoms themselves are made of protons, electrons, and neutrons.

no. of atoms = no. of moles * avogadros no. no. of atoms = 6 * 6*1023 no. of atoms = 3.6*1024 (ans)
Just one. A molecule is the smallest unit of a substance, so by just having "CO2" implies "1CO2". A coefficient is needed to indicate more than one molecule, such as "6CO2" which is six molecules of carbon dioxide.

18 carbon atoms (6 in each)

Well methane has a chemical structure of CH4 (one carbon surrounded by 4 hydrogen atoms), so for 2 methane you would need a total of 2 carbon atoms and 8 hydrogen atoms (or 4 H2 molecules)
