Answer: 13.776 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}{V_s}[/tex]
where,
n= moles of solute
[tex]V_s[/tex] = volume of solution in L = 1 L
moles of solute = [tex]\frac{\text {given mass}}{\text {molar mass}}=\frac{551g}{39.997g/mol}=13.776moles[/tex]
Now put all the given values in the formula of molarity, we get
[tex]Molarity=\frac{13.776moles}{1L}=13.776mole/L[/tex]
Thus molarity of this saturated NaOH (aq) solution is 13.776 M
