Answer:1 mol of Mg(NO3)2 contains 6.022*10^23 molecules

3 mol Mg(NO3)2 contains 3*6.022*10^23 = 1.81*10^24 molecules

Each Mg(NO3)2 molecule contains 2 N atoms  

Number of N atoms = 2*1.81*10^24 = 3.62*10^24 N atoms.

The number of atoms in 3 moles of nitrogen is; 6 atoms

According to the question:

  • We are required to determine the number of atoms in 3 moles of nitrogen.

Since nitrogen is a diatomic element;

This means that in it's natural state; Nitrogen is written as, N2.

As such, there are 3× 2 atoms of nitrogen in 3 moles of nitrogen.

We can then say we have 6 atoms of nitrogen in 3 moles of nitrogen.
