Please state the entire question - not just a part of it. Where was the number 3.407... obtained from ?david2120 said:using the number obtained 3.407x10^-8 coulombs/mole and the fact that one electron has a charge of 1.60x10^-19 coulombs, calculate how many electrons there are in one mole (i.e. Avogadro's number)
That doesn't look right to me (for one thing, it has units of [mole^-2] which are meaningless), but neither does the question as posted.I am not sure but do you do this problem like this?
3.407x10^-8coulombs/mole x 6.022x10^23electrons/mole divide 1.60x10^-19coulombs
The huge problem here is that you (improperly) used the number of electrons in a mole to determine...the number of electrons in a mole.david2120 said:using the number obtained 3.407x10^-8 coulombs/mole and the fact that one electron has a charge of 1.60x10^-19 coulombs, calculate how many electrons there are in one mole (i.e. Avogadro's number)I am not sure but do you do this problem like this?

Faraday's constant, denoted by the symbol F, is a physical constant that represents the amount of electric charge carried by one mole of electrons. It has a value of approximately 96,485.3329 coulombs per mole.
Faraday's constant is used in chemistry to calculate the amount of electric charge that flows through a system during an electrochemical reaction. It is also used to determine the number of moles of a substance produced or consumed in an electrolytic reaction.
Faraday's constant can be determined experimentally by performing an electrochemical reaction and measuring the amount of electric charge that flows through the system. This can be done using a device called a coulometer, which measures the amount of charge passing through a circuit.
Faraday's constant and Avogadro's number are related by the equation F = NAe, where N is Avogadro's number, A is the atomic mass of the element in grams, and e is the elementary charge of an electron. This relationship allows for the conversion between the number of moles of electrons and the number of atoms or molecules in a sample.
Faraday's constant is important in electrochemistry because it allows for the quantification of electric charge and the calculation of the amount of substance involved in an electrochemical reaction. It is also a fundamental constant in the field of electrochemistry and plays a crucial role in many chemical and industrial processes.
