Chemistry - Solid State Question with Solution | TestHub

Ionic solid $\left(N{a}^{+}{A}^{-}\right)$crystallizes in rock salt type of structure. 3g of ionic solid salt $\left(N{a}^{+}{A}^{-}\right)$is dissolved in water to make a 2L solution and the resulting solution has a pH ' 8 '. If distance between cation and anion is 250 pm , the density of ionic solid in $\mathrm{g}/\mathrm{cc}$ is:

$[$ Given : $p{K}_w=13,p{K}_a(HA)=5,N_A=6\times 10^{23}]$
