What is the potential difference across the capacitor?
1. The problem statement, all variables and given/known data
"Two 2.1cm x 2.1cm plates that form a parallel-plate capacitor are charged to +- 0.705 nC. What is the potential difference across the capacitor if the spacing between the plates is 1.20mm? "
2. Relevant equations
C = Q/V
C = epsilon * A/d
3. The attempt at a solution
I figure epsilon = 8.85 x 10^-12 F/m
A = area of plates = 0.021 * 0.021 m^2
d = separation of plates = 1.2 x 10^-3 m
And so I've tried plugging it all in and I still didn't get it right. In my attempts, I've tried answering with 2.17, 3.25*10^-12 , and 2.16*10^11 with no luck. Can anyone point out where I've gone wrong?

Have you calculated the potential difference or just tried numbers in random? Show your calculations in detail.

I did - but I apparently suffered a flurry of math errors. I got it anyway :)
