Coefficients in a chemical equation indicate the ratio of numbers of moles of molecules and atoms, which directly relates to the ratio of numbers of atoms and molecules involved in the reaction. They do not indicate the ratio of masses of molecules directly; mass ratios are determined by the molar masses of the substances involved and the coefficients.
