Atomic Mass of Nitrogen (N):
The atomic mass of nitrogen (N) is approximately 14.007 u.
Molecular Formula of Nitrogen Gas (N2 ):
Nitrogen gas consists of two nitrogen atoms bonded together. Therefore, its molecular formula is (N2 ).
Calculating Molar Mass:
Since nitrogen gas (N2 ) consists of two nitrogen atoms, we need to multiply the atomic mass of nitrogen by 2 to obtain the molar mass of (N2 )in grams per mole.
Calculation:
Molar Mass (N2)=2×Atomic Mass (N)× moles/grams
Given that the atomic mass of nitrogen (N) is approximately 14.007 u, we use this value in the calculation:
Molar Mass (N2 )=2×14.007u× moles/grams
Result:
After performing the calculation, the molar mass of (N2 )is approximately 2 ×14.007g/mol= 28.014g/mol.
So, the molar mass of N2 , which represents a molecule of nitrogen gas, is approximately (28.014g/moL.)
