Explanation:
As the given data is as follows.
Volume = 1.06 L,![\Delta T = -11.0^{0}C](/tpl/images/0171/8809/b885d.png)
Relation between temperature change and
is as follows.
where, c = concentration
i = Van't Hoff factor
When NaCl dissolves in water then it results in formation of sodium ions and chlorine ions. In means two ions are formed so, i = 2. Therefore, putting the given values into the above formula as follows.
c = 2.96
As molality is defined as number of moles of solute per kg of solvent.
So, mass of NaCl that should be added is calculated as follows.
= 183.54 g
Thus, we can conclude that mass of NaCl that should be added is 183.54 g.
