Answer» Correct Answer - PR T QT ST (A) Salicaldehyde `toC_(6)H_(4)(CHO)(OH)` or `C_(7)H_(^)O_(2) to 122 gm` / mole `n_(C_(7)H_(6)O_(2))=244/122=2` `n_(O)=2xx2=4` `n_(H)=6xx2=12` (B) `d_(O_(3))/(d_(CH_(3)))=((PMO_(3))/(RT))/((PM_(CH_(4))/(RT))=48/16=3` `(C) n=(PV)/(RT)=(3xx22.4)/(0.0021xx273) = 3` mole `n_(N_(2))=3` `n_(N)=6` (D) `Al_(2) (SO)_(3) to 342/342 =1 ` mole `n_(SO_(4)^(2)) =3` `n_("Total")=5` |
