Electrolysis can be used to determine atomic masses. A current of 0.550 A deposits 0.55g of a certain metal in 100 minutes. Calculate the atomic mass of the metal if eq. mass=molar Mass/3

A

100

B

45

C

48.25

D

144.75

Text Solution

Verified by Experts

The correct Answer is:
3

`(0.55)/(M)xx3=(0.55xx100xx60)/(96500)`
`rArr" "M=48.25g//mol`
