What is the molecular mass of Nitrogen?

Answer:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in atomic mass units (u). We can find the molecular mass of the molecule by

• Identify the formula of the compound or molecule
• Using the formula determine the number of atoms present in each element of the compound or molecule
• Multiply the atomic weight of each element with the number of atoms of that particular element
• Similarly, do it for all the elements in the molecule or compound
• Add up all the values obtained in the above step
• Then add the unit as grams/mole you will get the molecular mass of the substance

Molecular mass of Nitrogen

Nitrogen is a chemical element that has the symbol N and atomic number 7 and atomic mass 14.00674µ.

For nitrogen, the mass of the N₂ molecule is

N₂ = 14.01 + 14.01

N₂ = 28.02

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