The same two separate electrolytic was passed through two separate electrolytic cells containing solutions of nickel nitrate and chromium nitrate respectively . If 0.3 g of nickel was deposited in the first cell , the amount of chromium deposited is (At.mass of Ni= 59 , Cr = 52)

Answer»

`0.1` g
`0.17` g
`0.3g`
`0.6g`

SOLUTION :`("WT. of NI")/("Wt. of CR") = ("Eq. of mass of Ni")/("Eq. of mass of Cr")`
`(0.3)/("Wt. of Cr") = (59//2)/(52//3)` or Wt. of Cr = 0.17 g .
