1 ~g of silver gets distributed between 10 ~cm ³ of molten zinc and 100 ~cm ³ of molten lead at 800^ C . The percentage of silver in the zinc layer is approximately

Options

  1. A89
  2. B91
  3. C97
  4. D94

Correct answer

C. 97

Step-by-step solution

Concentration of Ag in zinc = x 10 Concentration of Ag in Pb = 1- x 100 x 10 1-x 100 =300 On solving, we get x =97 %
