Solution

c
$CaCl_2 \to Ca^{2+} + 2Cl^{-}$

વિયોજન પહેલાં	$1$	$0$	$0$
વિયોજન પછી	$1 -\alpha$	$\alpha$	$2 \alpha$

આપેલ, $w$ $= 20\,g$, $V$ $= 100\,mL$, $T$ $= 273\,K$,

$CaCl_2$ નું અણુભાર $= 111$

${\pi _{Normal}}\,\, = \,\,\frac{w}{{mV}}\,\, \times \,\,S\,\, \times \,\,T$

$ = \,\,\frac{{20\,\, \times \,\,1000\,\, \times \,\,0.821\,\, \times \,\,273}}{{111\,\, \times \,\,100}}\,\, = \,\,40.38\,\,atm$

$i\,\, = \,\,\frac{{1\,\, + \,\,2\alpha }}{1}\,\, = \,\,1\,\, + \;\,2\,\, = \,\,3\,\,\left( {\because \,\,\alpha \,\, = \,\,1} \right)$

${\pi _{\exp }}\,\, = \,\,1\,\, \times \,\,{\pi _{Normal}}$

${\pi _{\exp }}\,\, = \,\,40.38\,\, \times \,\,3\,\, = \,\,121.14\,\,atm$

વિયોજન પહેલાં	\(1\)	\(0\)	\(0\)
વિયોજન પછી	\(1 -\alpha\)	\(\alpha\)	\(2 \alpha\)
