The gram atomic mass of an element, also known as molar mass, is the mass of one mole of atoms of that element. It is numerically equal to the atomic mass of the element expressed in grams.
The atomic mass of nitrogen (N) is approximately 14 atomic mass units (amu) or 14 unified atomic mass units (u). Therefore, the gram atomic mass of nitrogen is approximately 14 grams per mole (g/mol).
This means that one mole of nitrogen atoms weighs approximately 14 grams. Similarly, one gram of nitrogen would contain approximately 1/14th of a mole of nitrogen atoms.
