That depends on the conditions the CH4 is subjected to. At STP, CH4 would be a gas with 22.4 liters/mole (0.0224 m3/mole) or 44.6 moles/m3. If you have it at cryogenic temperatures and high pressures like the atmosphere of Jupiter, the density will be different.

The number of moles of CH4 per cubic meter would depend on the density of methane at the given temperature and pressure. The ideal gas law, PV = nRT, could be used to calculate the number of moles if more information about the conditions is provided.
There are 6.5 moles of CH4 in 6.5 moles of CH4. Each mole contains Avogadro's number of molecules, regardless of the substance.
It depends on temperature,pressure and volume.THese are needed to find number of moles
There are approximately 2.34 x 10^24 atoms in 7.75 moles of CH4. This can be calculated by multiplying Avogadro's number (6.022 x 10^23 atoms/mol) by the number of moles.
To determine the limiting reactant, we need to compare the moles of reactants to the stoichiometry of the reaction. The balanced equation for the combustion of methane is CH4 + 2O2 -> CO2 + 2H2O. From the equation, 1 mole of CH4 requires 2 moles of O2. With 2.8 moles of CH4 and 5 moles of O2, the limiting reactant is O2 because it is in excess compared to the stoichiometry of the reaction.
Yes, there are two moles in one mole of CH4. This is because the chemical formula CH4 indicates that there is one carbon atom (which is one mole) and four hydrogen atoms (which combined are also one mole).
