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)

OpenStudy (aaronq):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

is this even correct?

OpenStudy (aaronq):

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