Each molecule of methane contains one carbon atom, as shown by the formula for methane, CH4. Therefore, the number of carbon atoms in one mole of methane is the same as Avogadro's Number, about 6.022 X 1023.
False, They contain the same number of molecules, not the same number of atoms. H2O contains 3 atoms, so in 1 mole of water there are 6.022*10^23 * 3 = 1.81*10^24 atoms. CH4 contains 5 atoms, so in 1 mole of methane there are 6.022*10^23 * 5 =3.01*10^24 atoms.
Using eight significant figures, there are 6.0221421 X 10^23 carbon atoms present in a mole of 12c.
A mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23. Therefore, a mole of ^12C contains 6.022 x 10^23 carbon atoms.
Since each mole of carbon dioxide molecules contains two moles of oxygen atoms, as indicated by the formula CO2 for carbon dioxide, half a mole of carbon dioxide will have one mole of oxygen atoms.
There are 6.022 x 10^23 atoms of argon in 1 mole of the gas, according to Avogadro's number.

The molecule of methane has 5 atoms.
False, They contain the same number of molecules, not the same number of atoms. H2O contains 3 atoms, so in 1 mole of water there are 6.022*10^23 * 3 = 1.81*10^24 atoms. CH4 contains 5 atoms, so in 1 mole of methane there are 6.022*10^23 * 5 =3.01*10^24 atoms.
