Answer: The molarity of solution is 7.45 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]
where,
n = moles of solute
[tex]V_s[/tex] = volume of solution in ml
moles of [tex]NaCl[/tex] = [tex]\frac{\text {given mass}}{\text {Molar mass}}=\frac{43.8g}{58.5g/mol}=0.745mol[/tex]
Now put all the given values in the formula of molality, we get
[tex]Molarity=\frac{0.745\times 1000}{100}[/tex]
[tex]Molarity=7.45M[/tex]
Therefore, the molarity of solution is 7.45 M
