mol/L^-1 vs. M
Are mol/L^-1 and M synonymous in this class? I noticed that both M and mol/L were used in the HW, so I'm wondering if there is a big difference.

Re: mol/L^-1 vs. M
Yes, they are the same thing. M is molarity which is equivalent to moles per liter and is a unit of measurement for concentration.

Re: mol/L^-1 vs. M
Reiterating was Devyn said, they are the same thing. One interesting thing to note though is that the SI unit of concentration is not M but is mole/cubic meter. But for this class I believe we will always be using molarity.

Re: mol/L^-1 vs. M
both are the same thing. If you calculate molarity then the units that you get is moles per liter

Re: mol/L^-1 vs. M
Yup these are all the same thing. Molarity (M) = mol/L = mol*L^-1 . You'll probably see all of these types used in different problems but they always mean the same thing! :)

Re: mol/L^-1 vs. M
mol/L is the units for M. M is the molarity and to calculate molarity it will be moles per liter or mol/L.

Re: mol/L^-1 vs. M
yes molarity aka M is representative of mol/L because M is mol of solute over liters of solvent and M is the simpler way of writing it. so both indicate the same meaning/unit.

Re: mol/L^-1 vs. M
Yes, molarity or molar concentration is equal to the number of moles within a solution in liters, which is mol/L or mol/L^1.

Re: mol/L^-1 vs. M
Yes, M, or molarity, is calculated by the number of moles over the volume, which is measured in liters. Therefore, m/L is equal to M :)

Re: mol/L^-1 vs. M
They are the same! Molarity (M) is mol/L which can also be written as mol*L^-1, so you can use either.
Hope that helps!
