One mole of any substance contains the same number of molecules, which is Avogadro's number (6.022 x 10^23). The molar mass of a substance is the mass of one mole of that substance. The molar mass of methane (CH4) is 16 g/mol, and the molar mass of oxygen (O2) is 32 g/mol. Therefore, one mole of methane has the same mass as half a mole of oxygen.
