In fact it's actually 96483 C (96500 is sometimes used to make approximate calculations)
The idea is to know how many electrons we need to have a total charge of 96483 C.
For this we divide the 96483 C by the charge of one single electron (i.e. the elementary charge=1.60217646 × 10-19 C).
So we have:
96483 C/1.60217646 × 10-19 C = 6.022 × 1023
The number to the right of the equals sign is nothing but Avogadro's number, which means that we need exactly one mole of electrons to get 96483 coulombs of charge.
According to IUPAC, 1 gram equivalent is the mass of a given substance which will:
* supply or react with one mole of hydrogen ions (H+) in an acid-base reaction; or
* supply or react with one mole of electrons in a redox reaction.
So, using the results of the calculation we made above, we can replace in the IUPAC definition (the second part) "one mole of electrons" by "96583 C of charge", and then the definition becomes the answer to your question.

What is the charge of the electorn?
The charge of neutron is 0, as it is neutral. The charge of proton is 1.6x 10 to the power -19 coulomb. The charge of electron is -1.6x10 to the power -19 coulomb.
How many proton in a coulomb?
One coulomb is equal to the force of repulsion when a unit positive charge is placed from a similar charge at a distance of 1m.
How many volts in 1 coulomb?
The charge itself has no mass - it is more like a property of objects, that do have charge. How much mass you need for one coulomb of charge would depend on whether you are talking about electrons, protons, etc.
How many electrons make up a charge of -58.0?
Charge on electron = - 1.602 X 10 -19 coulomb, so..., - 58. 0 coulomb/- 1.602 X 10 -19 coulomb = 3.62 X 1020 electrons ===============
What is the charge on the proton?
A proton has a positive charge of 1.602 x 10-19 coulomb.
What is the unit called a coulomb?
A coulomb, or ampere second, is the SI unit of electric charge. It is equivalent to the combined charge of 6.24 X 1018 protons.
What is the smallest unit of charge?
The smallest charge ever recognized is the charge of an electron, and it is equivalent to 1/94690 fraction of a coulomb.
How many electrons are in -1 coulomb?
The charge of 96,481 electrons; approximately counted as either 96,490 or 96,500 as per convenience has a charge equivalent to a Coulomb.
What is the charge in 1 coulomb?
The amount of charge in 1 Coulomb is exactly 1 Coulomb of charge. That's true whether the charge is positive or negative.
How much charge is in mega charge?
If we assume that by charge you mean coulomb (the SI unit for charge). Then we are looking for the value of one Mega Coulomb. The Mega prefix means 10^6(10 to the power of 6) therefore the charge in one Mega Coulomb is equivalent to 1*10^6 C or 1000000C (1 million Coulombs)
What is bigger- a coulomb or charge on an electron?
One Coulomb is the charge of about 6,241,510,000,000,000,000 electrons, so it looks likea Coulomb would probably be bigger than the charge on one electron.
What is dimensional formula of coulomb?
The Coulomb is a unit of electric charge. [Charge] is a fundamental quantity.
Which is bigger a coulomb or charge if an electron?
A coulomb is bigger. Please also note that a coulomb is defined as a POSITIVE charge, while an electron has a NEGATIVE charge. Anyway, the magnitude of a coulomb is much bigger than that of an electron.
How does a coulomb of charge compares with the charge of a single electron?
the charge of 1 coulomb is the charge associated with 6.25 billion billion electrons
Are the coulomb and ampere both units of charge?
coulomb is the unit of charge and ampere is unit of current
What is a Coulomb?
The coulomb is the SI unit of electrical charge. A coulomb, a unit of electrical charge, is defined as the amount of electric charge transported by a current of 1 ampere in 1 second. There are 6.241506×1018 electrons (or elementary charges) in a coulomb. A link is provided to the Wikipedia post on the coulomb.
How much time is required for 48.96 C of charge to move through an electric juicer if the current through the juicer is 1.39 A?
48.96 Coulomb/1.39 Coulomb/second = 35.223 Seconds
