As you calculated in Example 1, the molecular mass of ethanol is 46.069 amu. fadeoutDuration: 1, Haloalkanes or alkyl halides are organic compounds, which contain at least one halogen atom bonded to the carbon atom. Because the masses of individual atoms are so minuscule (on the order of 1023 g/atom), chemists do not measure the mass of individual atoms or molecules. It should be noted that not all .

Extending this into moles, for each mole of the compound, you'll have 2 mols of carbon, 6 mols hydrogen and 1 mol oxygen. Because of the way in which the mole is defined, for every element the number of grams in a mole is the same as the number of atomic mass units in the atomic mass of the element. @media only screen and ( max-width:480px ){ .ec_image_container_none, .ec_image_container_none > div, .ec_image_container_border, .ec_image_container_border > div, .ec_image_container_shadow, .ec_image_container_shadow > div{ min-height:310px; height:310px; } A Use the molecular formula of the compound to calculate its molecular mass in grams per mole.
