According to the question, a solution containing 1.9 g per 100 mL of KCl (M = 74.5 g mol–1 ) is isotonic with a solution containing 3 g per 100 mL of urea (M = 60 g mol–1 ).
As solution is isotonic,
{tex}\pi_1{/tex} (urea) = {tex}\pi _2 {/tex} (KCI)
{tex}\Rightarrow {/tex}C1RT = iC2RT
{tex}\Rightarrow {/tex}{tex}\frac { n _ { 1 } } { V 1 } = \mathrm { i } \frac { n _ { 2 } } { V 2 }{/tex} ({tex}\because {/tex}V1 = V2)
{tex}\Rightarrow {/tex}{tex}\frac { 3 } { 60 } = \mathrm { i } \times \frac { 1.9 } { 74.5 }{/tex}
{tex}\Rightarrow {/tex}i = 1.96
We know that, {tex}\alpha = \frac { i - 1 } { n - 1 }{/tex}
{tex}= \frac { 1.96 - 1 } { 2 - 1 } \\= 0.96{/tex}
= 96%

क्यूबा अमरीका के तट से लगा हुआ एक छोटा-सा द्वीपीय देश है। क्यूबा का जुड़ाव सोवियत संघ से था तथा सोवियत संघ उसे कूटनीतिक तथा वित्तीय सहायता देता था। 1962 में सोवियत संघ के नेता निकिता खुश्चेव ने क्यूबा में परमाणु मिसाइलें तैनात कर दीं। सोवियत संघ के इस रवैये से अमरीका क्रोधित हो उठा। फौरन अमरीकी के राष्ट्रपति कैनेडी ने आदेश दिया कि अमरीकी जंगी बेड़ों को आगे करके क्यूबा की तरफ जानेवाले सोवियत जहाजों को रोका जाए। ऐसा करके अमरीका सोवियत संघ को मामले के प्रति अपनी गंभीरता की चेतावनी देना चाहता था। ऐसी स्थिति में यह लगा कि युद्ध होकर रहेगा। इसी को क्यूबा मिसाइल संकट के रूप में जाना जाता है।
