Which of the following solution contains same molar concentration?A. `166 g. KI//L` solution.B. `33.0 g (NH_(4))_(2) SO_(4)` in `200 mL` solutionC. `25.0 g CuSO_(4).5H_(2) O` in `100 mL` solutionD. `27.0 mg Al^(3+)` per `mL` solution. |
Answer» Correct Answer - A::C::D `[{:(Mw "of" KI (NH_(4))_(2) SO_(4) CuSO_(4) 5H_(2) "and"),(Al^(2+) "respectively are" 166 132 250 "and"),(27 g mol^(-1)):}]` a. `M = (166 xx 1000)/(166 xx 1000) = 1.0 M` b. `M = (33 xx 1000)/(132 xx 200) = 1.25 M` c. `M = (25 xx 1000)/(250 xx 100) = 1.0 M` d. `M = (27 xx 10^(-3) xx 1000)/(27 xx 1) = 1.0 M` |
