If K_(sp) of CaSO_4. 5H_2O is 9xx10^(-6) . Find the volume of 1 gm CaS

1.	If K_(sp) of CaSO_4. 5H_2O is 9xx10^(-6) . Find the volume of 1 gm CaSO_4. (M.M = 136u)
Answer» 2.45 litre 5.1 litre 4.52 litre 3.2 litre Solution :`CaSO_(4(s)) HARR Ca_((aq))^(2+) + SO_(4(aq))^(2-)` `K_(SP)=S^2=9xx10^(-6)` `S=3xx10^(-3)` mole/litre mg/litre = M.M x S `=136xx3xx10^(-3)` `=408xx10^(-3)` GM/litre In 1 litre `408xx10^(-3)`gm `CaSO_4` `therefore` 1 gm `CaSO_4 = 1/(408xx10^(-3))`=2.45 litre
