If you had 15 molecules of carbon dioxide, you would have a total of 45 atoms present.
Reason:
A carbon dioxide molecule has a total of 3 atoms which are; 1 carbon atom and 2 oxygen atoms hence the name CO2. Since 1 molecule has a total of 3 atoms 15 molecules will have a total of 3*15 atoms, which is equal to 45 atoms.
As far as my knowledge goes this is logical and correct from my perspective.

Carbon Dixoide is CO2, there are 2 Oxygen and 1 Carbon atoms.
CO2's molar mass is 44g/mol, so 15/44=0.34mol CO2.
15 grams of CO2 is 0,341 moles.
30 molecules of oxygen
15 carbon molecules (C) react with 15 oxygen molecules (O2) to form 15 carbon dioxide (CO2)
2 atoms
three: one carbon and two oxygen
One carbon and 2 oxygens = 3
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.

2 atoms
no. of atoms = no. of moles * avogadros no. no. of atoms = 6 * 6*1023 no. of atoms = 3.6*1024 (ans)
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
three: one carbon and two oxygen
One carbon and 2 oxygens = 3
The chemical formula of carbon dioxide is CO2; the molecule contain one carbon atom and two oxygen atoms.
Carbon : 1 Oxygen : 2
One .. CO2 or O=C=0
What is listed are all examples of just onemolecule. O2 is one molecule of oxygen, CO2 is one molecule of carbon dioxide, and NH3 is one molecule of ammonia. Perhaps you're asking which has the largest number of atoms? In that case, the answer is ammonia, with a total of four atoms.
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.

Carbon Dioxide, or CO2, has one Carbon molecule and two Oxygen molecules.
