Calculate the amount in moles of silver deposited when 9650C of electricty is passed through a solution of silver salt [= 96500 Cmol-1]

A.

0.05

B.

10.80

C.

10.00

D.

0.10

Correct answer is D

m = \(\frac{Mm \times Q}{96500n
}\)

where Q = IT

M = Mm × \(\frac{Q}{96500n}\)

where m = mass

Mm = Molar mass

Q = Quantity of electricity

n = number of change= +1

\(\frac{M}{Mm}\) = mole = \(\frac{mass}{Molarmass}\)

\(\frac{M}{Mm}\) = \(\frac{Q}{96500n}\)

= \(\frac{9650}{96500n}\) × 1

= \(\frac{1}{10}\) = 0.1mol
