Degree of dissociation of pure water is 2.8 times 10^(-9), Molar ionic conductance of H^(+) and OH^(-) ions at infinite dilution are 300 and 350 S cm^(2) respectively. The molar conductance of water is _________.

Answer»

`1.5 times 10^(-6)S" "CM^(2)MOL^(-1)`
`2.8 times 10^(-7)S" "cm^(2)mol^(-1)`
`1.82 times 10^(-6)S" "cm^(2)mol^(-1)`
`3.8 times 10^(-6)S" "cm^(2)mol^(-1)`

Solution :`alpha=WEDGE^(C)/wedge^(@)`
`wedge^(C)=alpha times wedge^(@)`
`""=2.8 times 10^(-19) times (300+350)`
`""=1.820 times 10^(-6)`
