Kindly go through the solution 

AICI₃ has greater number of ions, therefore it shows the highest osmotic pressure.

${\pi }_1=iCR{T}_1$

${\pi }_2=iCR{T}_2$            

$\frac{{\pi }_1}{T_1}=\frac{{\pi }_2}{T_2}$            

${\pi }_2=\frac{{\pi }_1*T_2}{T_1}$            

$=\frac{7*10^5*283}{273}$                  

= 7.256 * 10⁵ * Pa

= 72.56 * 10⁴ Pa

p₂ = x * 10⁴

x = 72.56 » 73

Assume mass of solution

= 100g

Mass of solute = 36gm

Moles of solute = 1

Molarity=  $\frac{1*1000}{\left(\frac{100}{1.5}\right)}=\frac{1000}{100}*1.5=15$

As NaCl is strong electrolyte, its degree of dissociation (a) will remain same.

            I = 2

            For each sample,

            i₁ = i₂ = i₃

Higher the value of (ixM), higher will be the boiling point of solution.

If a solution containing more than 0.9% salt is used, and we place blood cells in it, the water will flow out of the cells, and they will shrink. Such a solution is a hypertonic solution.

Similarly, if a solution contains less than 0.9% salt, the water will flow into the cells, and they will enlarge.
