my some questions whose confuse me

1. in literature some researcher says we can calculate the specific capacitance in unit of F/g by using three electrode system by equation which is given below:

integrated area on the curve cv/ 2* mass* potential window* scan rate

but some researcher says we can calculte the specfic capacitance in unit F/g by using three electrode system by equation which is given below:

integrated area on the curve cv/ mass* potential window* scan rate

but not divide by 2 . which one is correct ?

2. area under the curve is calculated in cv all of its parts mean capacitive current , faradic current , anodic and cathodic or only anodic part i upload a cv curve with its part ?

3. who can we calculate the areal capacitance of electrode if i deposited the active materiel on nickel form area 1 cm2 on the both sides ? my question is that we divide the capacitance by 2 or 1 in replace of mass in above equation.

4. in gamry software we calculate area under the curve of unit coulomb but this can not satisfied the above equation such as

Cs = coulmb/ gram* volt* milivolt/ second = coulmb *time /gram* (volt)2

which is not equal to F/g why ?
