To within 1 part in almost 800, the densities of methanol and ethanol are the same.That means the same volume of each will contain the same mass of each. Methanol molecules have a relative molecular mass of 32, while ethanol molecules have a relative molecular mass of 46, so you get more methanol molecules than ethanol molecules in the same mass (or volume). To get the same number of ethanol molecules as you would have had methanol molecules, multiply the mass or volume of methanol you would have used by 46/32.
