The mass of 1 mole of nitrogen atoms can be determined by using the molar mass of nitrogen.

Molar Mass of Nitrogen:
The molar mass of an element is the mass of one mole of atoms of that element. Nitrogen (N) has an atomic number of 7, which means it has 7 protons and 7 electrons. The atomic mass of nitrogen is approximately 14.01 atomic mass units (amu).

Explanation:
To calculate the molar mass of nitrogen, we need to consider the atomic mass of nitrogen and the concept of moles. The atomic mass of nitrogen is given in atomic mass units (amu), which is defined as 1/12th the mass of a carbon-12 atom.

Using Avogadro's Number:
Avogadro's number (6.022 x 10^23) is the number of atoms or molecules present in one mole of a substance. It is a fundamental constant in chemistry and is used to convert between the number of moles and the number of atoms or molecules.

Calculation:
To find the mass of 1 mole of nitrogen atoms, we multiply the molar mass of nitrogen by Avogadro's number.

Mass of 1 mole of nitrogen atoms = Molar mass of nitrogen x Avogadro's number
= 14.01 amu x 6.022 x 10^23 atoms/mol

When we calculate this, we find that the mass of 1 mole of nitrogen atoms is approximately 14.01 grams.

Summary:
In summary, the mass of 1 mole of nitrogen atoms is approximately 14.01 grams. This is calculated by multiplying the molar mass of nitrogen (14.01 amu) by Avogadro's number (6.022 x 10^23 atoms/mol). The molar mass of an element is the mass of one mole of atoms of that element, and Avogadro's number is a constant that relates the number of atoms or molecules to the number of moles.
