Yes, it's the third. Take 96,484.56/6.022045 x 10^23 = 16,021.892 x 10^-23 or 1.6021892 x 10^-19
Baloney! It's just a math problem. What a lousy excuse!
yay for more hw help! please!

Not to offend, but what has your teacher been teaching you? What grade are you in?
This is really basic stuff... but you need to be able to do is understand the question.
Get out a highlighter, pick out the important parts of the question to help you comprehend what is going on - then just cancel down the units til you get what you one.
Charge on one mole = 96484.56 C (coulombs per mole)
6.022045x10^23 electrons in one mole (electrons per mole)
Follow the units for the first divide the second
coulombs/mol divide electrons/mol = coulombs per electron

So what are you doing for calculus and statistics? Don't know how it is at your school but every bio major I know of has to take a full sequence of chemistry and those two math classes at least...
I have a degree in bio and we had to take chem, calculus and physics in addition to all the bio courses.
I still have nightmares! lol
as far as the questions go, as stated above, the answer is the second one.
they tell you the charge per mole of electrons, they tell you how many electrons (particles) are in the mole.
they ask you to compute the charge on a single electron in that mole.
so, its a division problem.
always check units. in almost all chem problems, if the units don't cancel out properly, something is wrong.

Have not taken those yet lol. I know I'll be taking Calc as well as Physics.
