0.002m aqueous solution of an ionic comp...

`0.002m` aqueous solution of an ionic compound `Co(NH_(3))_(5)(NO_(2))CI` freezes at `-0.00732^(@)C`.Number of moles of ions which 1 mole of ionic compound produces in water will be `(K_(f) = 1.86^(@)C//m)`

Text Solution

Verified by Experts

`DeltaT_(f)=iK_(f)m`
`:.i=(DeltaT_(f))/(K_(f)xxm)=(0.00732)/(1.86xx0.02)=2`
