Methane has a molecular weight of 16 and 4 atoms per molecule. Oxygen (O2O2) has a molecular weight of 32 and 2 atoms per molecule.
32g of something with a molecular weight of 16 is 2 moles — since there’s 4 atoms, that’s 8 moles of atoms. Since oxygen molecules have 2 atoms each, 8 moles of atoms yields 4 moles of O2O2 molecules. Since they are 32g per mole of O2O2, 4 moles x 32g / mole = 128g
