Answer:
ampere = 15.95 mA
Explanation:
given data
deposit gold = 0.560 g
time = 4.70 hour = 16920 s
solution
we get here moles of gold that is
moles of gold = 0.560 g ÷ 196.967 g/mol
moles of gold = 0.0028
moles of gold = 0.0028 ( 1 Faraday / 1 mol )
moles of gold = 0.0028 Faradays
moles of gold = 0.0028 Faradays × 96500 Coulom/ faraday
moles of gold = 270.2 coulombs
and we get here ampere that is
ampere =
ampere = 0.01596 A
ampere = 15.95 mA
