The vapour density of completely dissociated NH_(4)C1 would be

Answer»

Slight less than half that `NH_(4)C1`
Half that of `NH_(4)C1`
Double that of `NH_(4)C1`
Determined by the AMOUNT of SOLID `NH_(4)C1` in the experiment

Solution :`("Normal MOLECULAR weight")/("experimental molecular wt.") =1+ALPHA`
`NH_(4)C1hArrNH_(3) + HC1`
`.: alpha = 1`
`:.` "Experimental Molecular wt". `= ("nor.mol.wt.")/(2)`
