how do you find the mass of a nitrogen molecule?

find the molecular mass (N2), which in grams is the mass of a mole of nitrogen molecules, so dividing by avagradros number will give the mass of a single N2.

so it is 28g/avagradro's number right?

yes, that is the mass of one N2 molecule.

To find the mass of a nitrogen molecule, you need to know the atomic mass of nitrogen and then multiply it by the number of nitrogen atoms in the molecule.

Step 1: Determine the atomic mass of nitrogen. This is usually given on the periodic table and is typically around 14.01 atomic mass units (amu).

Step 2: Identify the number of nitrogen atoms in a nitrogen molecule. Since a nitrogen molecule (N2) consists of two nitrogen atoms bonded together, the number of nitrogen atoms is 2.

Step 3: Multiply the atomic mass of nitrogen by the number of nitrogen atoms. In this case, 14.01 amu × 2 = 28.02 amu.

Therefore, the mass of a nitrogen molecule (N2) is approximately 28.02 atomic mass units.
