Static Electricity Problem

jmail

So, I'm in first year university physics and each week we have online quizzes. And I'm having trouble figuring out how I got this question wrong.

Q: In what amount of nitrogen gas are 0.8 MCb of negative charge? Note: each nitrogen atom has 7 electrons.

The answer they gave is 5.92 x 10^(-1) mol
but I'm not getting this answer, and I've tried so many times.

I keep on getting 1.19 x 10^(0) mol.
---> What I did was find Q by = (7)(1.6 x 10^-19)(6.02 x 10^23) = 6.74 x 10^(5) Cb/mol
---> Then to find n I did = 0.8 x 10^6 / 6.74 x 10^5 = 1.19

If anyone could help me, that would be great. This problem is really bothering me.
THANKS :)

Remember nitrogen gas is N2

i think maybe this should be moved to the homework forums?
