10800C of electricity past through the electrolyte deposited 2.977 g of metal with atomic mass `106.4 g mol^(-1)`. Find the charge on the metal cations.

Text Solution

Verified by Experts

The correct Answer is:
4
`10800 e to 2.977 , " Charge " xx 96,500 to 106.4`
`"Charge" xx 96,500 xx 2.977 = 106.4 xx 10800`
Charge `=(106.4 xx 10800)/( 96500 xx 2.977) = 3.94 = 4 `
