Answer:
2 atoms of nitrogen are present.
Answer:
1.811 g
Explanation:
The computation of the mass need to use to make the solution is shown below:
We know that molarity is

So,


= 0.031 moles
Now

where,
The Molecular weight of NaCl is 58.44 g/mole
And, the moles are 0.031 moles
So, the mass of NaCL is

= 1.811 g
We simply applied the above formulas
