The format came out wrong - the double bond of oxygen to carbon occurs at the first apex.

Thanks! and you do mean that it is 0.0123 moles, therefore I would plug in 3 for M, and 0.0123 for moles so that implies 3 x L = 0.0123 --> 0.0123/3 = L = .0041 L ~ 4.0mL ?

E = k*Q/(r*sqrt(r^2+(L/2)^2) now L/r<1 then L^2/r^2 is approximately 0 therefore take out r E= k*Q/[r*r(sqrt(1+L/2r)^2)] sqrt(1+L/2r)^2)= sqrt(1) E = k*Q/r^2 therefore the answer is point charge ... it goes like r^-2
