0.55 A of current gets deposited on 0.55...

0.55 A of current gets deposited on 0.55 g of a certain metal in 100 minutes. What is the atomic mass of the metal?
(Given, equivalent weight `=("atomic weight")/(3)`)

A

100

B

45

C

48.24

D

144.75

Text Solution

Verified by Experts

The correct Answer is:
C
Charge `=0.55 xx 100 xx 60 =3300 C`
3300 C deposites 0.55g
96500 C deposits `(0.55)/(3300) xx 96500 g = 16.08g`
Eq. mass : Mass deposited by IF (96500 C)
Eq. wt. `=("Mol.wt")/(3)`
`16.08=("mol. wt")/(3) , "mol. wt."=48.24`
48.24
