**[SOLVED] Gauss's Law and Flux**

ok so i have the biggest question of all i tried solving the following problem:

55.3 million excess electrons are inside a closed surface. What is the net electric flux through the surface?

now i tried the following equations:

[tex]\Phi[/tex]= E . A = Qin/[tex]\epsilon[/tex]

but i have the biggest question when there is excess electron does it mean that the electron field is negative, and if it does then that goes in Qin where then [tex]\Phi[/tex] would be equal to Qin/[tex]\epsilon[/tex], and epsilon being 8.85*10 (permittivity constant)

well any help in solving this problem is very grateful
