Alternatively, the relative atomic mass of an element is given by the mass of one atom of the element1/12 of the mass of one atom of carbon-12 2 Thenumber of atomscontained in the relative atomic mass of an element has been shown byAvagardro to be 6.02×1023. This number is called...
The atomic mass of each element is added together to find the number of grams in one mole. This is called the molar mass and can be used to convert from mass to moles. For example, to find the molar mass of H2O, find the mass of two hydrogen atoms and one oxygen atom and add ...
