Observed molecular mass of silver nitrate is 92 . The degree of dissociation of $AgNO_{3}$ is

Question

Professor PC Thomas Classes · Answer

van't Hoff factor, $i=\frac{	ext { Calculated }}{	ext { Observed }} \frac{	ext { molecular mass }}{	ext { molecular mass }} i=\frac{170}{92}=1.85 AgNO_{3} \leftrightharpoons Ag^{+}+NO_{3}^{-} 1-\alpha \quad \alpha \quad \alpha 	ext { Total number of moles }=1+\alpha i=\frac{1+\alpha}{1}=1+\alpha \alpha=i-1=1.85-1=0.85$
