At 291 {\K} , saturated solution of {\BaSO}_{4} was found to have a specific conductivity of 3.648 \times10^{-6} {\ohm}^{-1} {\cm}^{-1} and that of water being used is 1.25 \\times10^{-6} {\ohm}^{-1} {\cm}^{-1}. If the ionic conductance's of {\Ba}^{2+}and {\SO}_{4}^{2-} are 110 and 136.6 {\ohm}^{-1} {\cm}^{2} {\mol}^{-1} respectively, the solubility of {\BaSO}_{4} at 291 {\K} will be [Atomic masses of {\Ba}-137, {\S}-32,0-16]

Correct Answer is : 2.266×10−3gL−1

At 291K , saturated solution of BaSO4 was found to have a specific conductivity of 3.648×10−6ohm−1cm−1 and that of water being used is 1.25×10−6ohm−1cm−1. If the ionic conductance's of Ba2+and SO42− are 110 and 136.6ohm−1cm2mol−1 respectively, the solubility of BaSO4 at 291K will be [Atomic masses of Ba−137,S−32,0−16]
