What is mass?

The quantity of matter in a thing is measured by its mass. Typically, mass is expressed in kilogram (kg) or gram (g) .

Calculation of mass:

Mass can be calculated by using the formula.

Mass = mol × molar mass

Mass = 13.6 × 56 +(3× 14) +(9 × 16).

Mass = 242 g.

Therefore, the mass of nitrogen will be 242 gram.
