Electrons in GRAMS :(
Part1:
A sample of electrons is found to have a total charge of -7.68 x 10^8 C.
How many electrons are in this sample ?
===================================
Part 2 says:
What is the mass of the above sample of electrons in grams ?
1 electron mass = 9.10938188 × 10^-28 grams]
for part 1 My answer was 4.79e27. And its CORRECT
for part 2 i keep getting 4.36 as an answer but its wrong.
I used [1 electron mass = 9.10938188 × 10^-28 grams]
and multiplied that by my answer for part 1.
PLEASE HELP, Thanks.
