Correct Answer - B
`^^_(K+)^(oo)+^^_(Cl^(-))^(oo)=152Scm^(2)mol^(-1)` . . .(1)
`^^_(Na^(+))^(oo)+^^_(Cl^(-))^(oo)=128Scm^(2)mol^(-1)` . . .(2)
`^^_(K^(+))^(oo)+^^_(NO_(3)^(-))^(oo)=111Scm^(2)mol^(-1)` . . .(3)
अब, `^^_(NaNO_(3))^(oo)=^^_(NaCl)^(oo)+^^_(KNO_(3))^(oo)-^^_(KCl)^(oo)`
`^^_(NaNO_(3))^(oo)=128+111-152=87Scm^(2)mol^(-1)`
