Problem

A jeweler operates a silver-plating cell at a steady

0.800\,\text{A}

for

25\,\text{min}

. The current efficiency of the cell is

88.0\,\%

. For the half-reaction

Ag^+ + e^- \rightarrow Ag(\text{s})

, what mass of Ag(s) should the jeweler expect to collect? (Faraday constant:

F = 9.65 \times 10^{4}\,\text{C mol}^{-1}

; atomic mass of Ag =

107.9\,\text{g mol}^{-1}

) (a)

1.34\,\text{g}

(b)

0.14\,\text{g}

(c)

1.18\,\text{g}

(d)

1.52\,\text{g}
