The gram molecular mass of carbon dioxide is about 44.01 grams. By definition, this value is the number of grams of carbon dioxide that contains Avogadro's Number ("AN") of molecules. Avogadro's Number is about 6.022 X 10^23. Therefore the number of molecules in 1 gram is (1/44.01)(AN) or 2 X 10^21 molecules, to the justified number of significant digits.
1.0 grams carbon dioxide (1 mole CO2/44.01 grams)(6.022 X 10^23/1 mole CO2)
= 1.4 X 10^22 molecules of carbon dioxide

Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432
Carbon Dioxide, or CO2, has one Carbon molecule and two Oxygen molecules.
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).
11 grams because all is reacted and there is no reactant left over, although if there were only 3 grams of carbon there would have to be 6 grams of oxygen for this to be viable as carbon dioxide is CO2 so the question asked was itself wrong.
Look up the molecular weight of carbon dioxide in the periodic table. The formula for carbon dioxide is CO2, which means one atom of carbon and two atoms or oxygen per molecule of carbon dioxide. Carbon has molecular weight of 12. Oxygen molecular weight is 16. Total 12+16+16= 44 11 grams/44 grams/mole=0.25 moles of carbon The grams of water and combustion of 7.5 grams are totally irrelevant. They are only given to possibly confuse you.
Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432
2,22 1023 molecules of carbon dioxide is equal to 0,368 moles.

22 grams carbon dioxide (0.5 moles)
The mass of carbon dioxide is 141,2 g.
Ethane does not have any molecule of carbon dioxide. However when ethane undergoes combustion then two molecules of carbon dioxide are formed (as ethane contains two carbon atoms).
there is no hydrogen in carbon dioxide. since carbon dioxide is CO2 there are 3 carbon and 6 oxygen atoms in three molecules.
I think there are 400 carbon molecules
7.30 moles carbon dioxide (6.022 X 10^23/1 mole CO2) = 4.40 X 10^24 molecules of carbon dioxide
2.10 moles carbon dioxide (6.022 X 1023/1 mole CO2) = 1.26 X 1024 molecules of carbon dioxide ==============================
