Upon fully dissolving 2.0 ~g of a metal in sulfuric acid, 6.8 ~g of the metal sulfale is formed. The equivalent weight of the metal is -

Options

  1. A13.6 ~g
  2. B20.0 ~g
  3. C4.0 ~g
  4. D10.0 ~g

Correct answer

B. 20.0 ~g

Step-by-step solution

Equivalents of metal = Equivalents of metal sulphate wt.of metal Eq.wt.of metal wt.of metal sulphate Eq. wt.metal sulphate array l 2 x = 6.8 x+48 6.8 x=2 x+96 4.8 x=96 x= 96 4.8 =20 array
