Answer» `1.08xx10^(-10) "mol"^(2)L^(-2)` `=(2.42xx10^(-3))/(233) "mol" L^(-1)` `=0.0104xx10^(-3) "mol" L^(-1)` `=1.04xx10^(-5) "mol" L^(-1)` `{:(BaSO_(4) ,hArr,Ba^(2+),+,SO_(4)^(2-)),(,,S,,S):}` `K_(sp)=[Ba^(2+)][SO_(4)^(2-)]=SxxS=S^(2)` `=(1.04xx10^(-5) "mol" L^(-1))^(2)` `=1.08xx10^(-10) "mol"^(2)L^(-2)` |
