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
[tex]Molarity = \frac{Number\ of\ moles}{Volume\ in\ L}[/tex]
So,
[tex]Number\ of\ moles = Molarity\ \times Volume\ in\ L[/tex]
[tex]= 0.223\times 0.141[/tex]
= 0.031 moles
Now
[tex]Mass = moles \times Molecualr\ weight[/tex]
where,
The Molecular weight of NaCl is 58.44 g/mole
And, the moles are 0.031 moles
So, the mass of NaCL is
[tex]= 0.031 \times 58.44[/tex]
= 1.811 g
We simply applied the above formulas
