Question

If a piece of jewelry were electroplated with gold for 25 seconds at 1.5 A, how many grams of gold would be plated?
(Note: 1 A = 6.241 1018 e–/s. The reaction for the reduction of gold ions to gold metal is Au+ + 1e– Au(s).) (1 point)

Answer 1

Find the atoms reduced

\(1A=6.241∗10^{18}~e–/s\)

So, \(1.5(6.241∗10^{18}e–/s)*25~s\)=number of atom reduced

convert to moles then to grams

Answer 2

so this gets to be number of atom reduced = 2.34 E 20

Answer 3

is this even correct?

Answer 4

yep, these are atoms, so it's not surprising that it's a very large number. That number is not even a mole.
