What is the relationship between the molar mass and atomic mass?
The molar mass is the mass of a molecule - sum of the masses of contained atoms, expressed in grams.The atomic mass is the mass of an isotope expressed in unified mass atomic units.The atomic weight is the mass of a chemical element (taking into account its isotopes) expressed in unified mass atomic units; also known today as relative atomic mass. IUPAC maintain the term (standard) atomic weight.
How would we know how many moles are in a certain element?
number of moles = mass of the element/molar mass of the element
Calculate the atomic mass of an element?
By taking the wieghted averages of naturally occurring isotopes of that element. :)
