MCQ
The $2\,N$ aqueous solution of ${H_2}S{O_4}$ contains
  • A
    $49\, gm$ of ${H_2}S{O_4}$ per litre of solution
  • B
    $4.9\, gm$ of ${H_2}S{O_4}$ per litre of solution
  • $98\, gm$ of ${H_2}S{O_4}$ per litre of solution
  • D
    $9.8\, gm$ of ${H_2}S{O_4}$ per litre of solution

Answer

Correct option: C.
$98\, gm$ of ${H_2}S{O_4}$ per litre of solution
c
(c) Wt. of ${H_2}S{O_4}$ per litre $ = \,\,N \times {\text{eq}}{\text{.}}\,\,{\text{mass}}$$ = {\text{2}} \times {\text{49}}= 98\,g.$
