How do you calculate the number of moles in methane?
- find how many of each element ( C and H ) is present in the compound.
- multiply the number of C atoms by the relative atomic mass of C (masses can be found on most periodic tables)
- multiply the number of H atoms by the relative atomic mass of H.
- sum the total.

What is the mole formula?
Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

Why does 1 mole of any gas occupy the same volume?
Avogadro’s law states that “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.” For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
