Answer:
0.817g
Explanation:
Zn2+ + 2e -----> An
Amount of electricity used
Q = It
= 1.6A x 25 x 60 seconds
= 2400 coulomb's
Number of moles of electrons = Q/f
F = 96500 coulomb's
= 2400/96500
= 0.025mol
From the equation above,
We see that the number of Zn moles firmed is equal to half the number of electrons used.
Molecular weight of Zn = 65.38
0.025x65.38/2
= 0.817 grams of zinc
Thank you!
