Theresistance of 1N solutionof acetic acidis 250 omegawhenmeasuredin a cell having a cell constant of1.15 csm^(-1)The equivalent conductance (in "ohm"^(-1) cm^(2)"equiv"^(-1)) of 1N acetic acidis

Answer»

2.3
4.6
9.2
18.4

Solution :Equivalentconductivity `(wedge_("eq"))=(kxx1000)/(C )`
conductivity (k) `=("cell CONSTANT ")/("Resistance") =(1.15 )/(250) S CM^(-1)`
`thereforewedge_(eq)=(1.15 xx1000)/(250 xx1) =4.6 "ohm"^(-) cm^(2) "eqiv"^(-1)`
