A 0.101 M solution of Ba3PO42 is isotonic with 0.004 M glucose solution. The degree of dissociation and van't Hoff factor of Ba3PO42, respectively, are

$i = \frac{Π}{(Π)_{0}} = \frac{(0.004 M) R T}{(0.001 M) R T} = 4; α = \frac{i - 1}{v - 1} = \frac{4 - 1}{5 - 1} = \frac{3}{4} = 0.75$

Thus, the degree of dissociation and van't Hoff factor of ${Ba}_{3} {({PO}_{4})}_{2}$ , respectively, are 4 and 0.75.
