Vattenmolekyl H2O - Molekylmassa, molmassa - Convertworld

So 1 g water will contain 1/18 moles of H2O molecules. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass ( molar weight ) is the mass of one mole of a substance and is expressed in g/mol. Atomic weight of hydrogen is 1,008. Atomic weight of oxygen is 15,999. The sum is the molar mass of H2O: 18,015 g.
