Answer 2

Answer:

Nitrogen is a chemical element that has the symbol N and atomic number 7 and atomic mass 14.00674µ. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in atomic mass units (u).

For nitrogen, the mass of the N2 molecule is (14.01 + 14.01) = 28.02

Thus, the molecular mass of a nitrogen molecule = 28 u
