Query: In electromagnetism, charge density is a measure of electric charge is the amount of electric charge per unit length, surface area, or volume, called the linear, surface, or volume charge density, respectively. The respective SI units are C⋅m, C⋅m or C⋅m.
electromagnetism has to do with charge

Electric field vectors can have a direction.
your electric field vector is not useful
Electric flux isn't not not found using vectors.
density is harder to find 
The serving size is measured in metric terms
Charge density is measured in Coulomb's times meters.
Charge density SI units are in Calories per meter (c x m)
electromagnetism has to do also with the linear surface
