Explanation:

Zn

2+

+2e

⟶Zn

1 mole is deposited by 2×96500=193000C

The charge supplied = 0.965×10×60=579C

∴ Number of moles deposited =

193000

579

=0.003 moles

In 500ml, number of moles =

1000

500

×0.2=0.1 moles

∴ Moles remaining in the 500ml solution = 0.1−0.003=0.097 moles

∴ Molarity =

500

1000

×0.097=0.194M
