Question:
One gram of silver gets distributed between 10 cm3 of molten zinc and 100 cm3 of molten lead at 800 o C. The percentage of silver in the zinc layer is approximately
(Given: Partition coefficient of Ag in Zn and Pb is 300)
(a) 89
(b) 91
(c) 97
(d) 94
Solution: (c)
Let mass of Ag in Zn = x g
