mol/L^-1 vs. M

Postby Sean1F » Sun Jan 16, 2022 1:36 am

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.

Yes, they are the same thing. M is molarity which is equivalent to moles per liter and is a unit of measurement for concentration.

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.

both are the same thing. If you calculate molarity then the units that you get is moles per liter

mol/L is basically the unit of M, and you can solve for M using mol/L

Molarity is the same as moles/Liter :)

Yep! They're the same, just different notations.

Hi! Yes they are the same thing. M=moles/volume so M is the same as mol/L.

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! :)

They are the same thing, just different ways of writing it.

mol/L is the units for M. M is the molarity and to calculate molarity it will be moles per liter or mol/L.

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.

Both m/L^-1 and are the same, they are usually units for concentration

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.

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 :)

Like the others have stated M, molarity, is the same as mols/L^-1.

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!

Like most peers have states the units of M is mol/L. :)

Molarity is in the units of mol/L so it's just the same thing.
