### Re: n value

n is moles so I assume it will either be a given value or we will need to convert to moles from a given mass of a compound or element.

### Re: n value

n is just the amount of moles present, so the problem will give you that information or a way to calculate it.

### Re: n value

n is the moles of the compound given or calculated for; however, do not confuse this with nr, which is a pure number with the unit mol struck out. Nr is just the stoichiometric coefficient in the reaction equation.

### Re: n value

n is the number of moles so it would either be given to us or we calculate it using molar mass or using the ideal gas law( in which case Pressure Volume and Temperature will be given.)

### Re: n value

In this equation, n is the moles of electrons transferred within the redox reaction.

### Re: n value

n is the change in moles of the reaction so you can look at the two sides of the reaction and see the difference

### Re: n value

the textbook says that n in this equation is the number of miles of electrons transferred in the reaction.

### Re: n value

N is the number of moles of electrons in the balanced redox reaction.

### Re: n value

n isn't just moles and probably isn't given in the problem. n is moles of electrons transferred once you balance the redox half reactions

### Re: n value

I believe n can be the change of moles in the equation or the number of electrons transferred.

### Re: n value

n is the number of electrons that cancel out when you write out oxidation/reduction half-reactions to get the balanced redox reaction
