Correct Answer - C
Phosphorus reacts with limited `Cl_(2)` as:
`P_(4)+6Cl_(2)rarr4PCl_(3)" …(i)"`
`PCl_(3)` is hydrolysed as :
`(PCl_(3)+3H_(2)OrarrH_(3)PO_(3)+3HClxx4)/(P_(4)+6Cl_(2)+12H_(2)Orarr4H_(3)PO_(3)+12HCl)" ....(ii)"` ltbr Moles of white `P=(62)/(124)=0.5` mol
1 mol of white `P_(4)` produces = 12 mol of HCl 0.5 mol of white `P_(4)` will produce `12 xx 0.5 = 6` mol of HCl Mass of `HCl = 6 xx 36.5 = 219 g`
