Mass of atoms equation

WebThe mass of an atom can be expressed by a unit called atomic mass unit (amu), which is the mass of 1/12th of the mass of a neutral, non-bonded carbon. Using this unit, we can say that the helium atom has a mass of 4.0026 amu. The proton has a mass of 1.00727 amu, while the neutron has a mass of 1.00866 amu. What is the mass defect of the helium? WebThe number of atoms of ANY substance in a volume is: # of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro's number and its equal to 6.022*10 23 atoms/ mole. It can also be molecules per mole. In the above formula density times volume is just the mass.
