If 0.5A current is passed through silver nitrate solution for 3 mins and 20 s, 0.1183 g of silver is deposited. What is the chemical equivalent of silver?

$2.183 \times 10^{-6} \mathrm{~kg}-C^{-1}$

$0.183 \times 10^{-6} \mathrm{~kg}^{-C^{-1}}$

$1.56 \times 10^{-6} \mathrm{~kg}-\mathrm{C}^{-1}$

$1.183 \times 10^{-6} \mathrm{~kg}^{-\mathrm{C}^{-1}}$
