### V=n/c

In the equation V=n/c, what does the 'n' represent?

n is the moles of solute

That equation is derived from the equation c = n/V where c represents the molarity of a solution, n the moles of the substance being dissolved and V represents the volume of the solution.

On an extended note for this -
What is the difference between M and m? All of the similar variables are confusing me... If someone is interested in simply laying out all the different variables related to Molarity that would be amazingly helpful!

I'm not sure if "m" is used for molarity, but I think M refers to molarity (molar concentration), and "m" is used to denote the units for meters and I guess "m" can also be used to symbolize mass??

During Professor Lavelle's lecture, he also said that he would use M to represent molarity concentration. However, in the textbook (at least in the 6th edition), molarity concentration is represented as the variable "c".

To answer the above extended question of the difference between m and M, I believe that m represents the molar mass of an element, while M represents the molarity of the element.

### Re: V=n/c

I think in my discussion our TA wrote molar mass out as Mr (but that might just be what she does) where as molarity is always a capital M. I would make sure you don't mix that up in because there are other equations in chemistry such as p=mv for momentum problems where m=mass.
