mol vs. mmol

[anthony_trieu2L]

What is a mmol? In some of the practice questions in G we are given the unit mmol.

[Chase Yonamine 1J]

1mmol is equal to 1x10^-3 mol. the m in front mmol means milli or 10x^-3.

[Nathan Mariano 2G]

The prefix "milli-" denotes multiplication by 10^-3. One millimole is equivalent to 10^-3 moles.

In an exam would we ever have to convert from mol to mmol or vice-versa?

From what I've seen in my chemistry career so far (Chem Honors and AP Chemistry), I have never seen any question ask for the moles of a molecule/atom as mmol. It is almost always simply in moles. However, if you were to convert from mol to mmol, multiply by (1000 mmol/1mol). To convert from mmol to mol, multiply by (1mol/1000mmol).

The conversion from mol to mmol is fairly trivial, you should be confident in doing that conversion! As has been said, 1mmol=1x10^-3mol. You should always be prepared to convert between units in chemistry. As Dr. Lavelle said, chemists like stuff like Angstroms sometimes, so it is within reason that you could be asked to do conversion between any order of magnitude. For example, if you find the liters of something, we could fairly ask you to convert that to picoliters if we wanted to (odd example, but the point stands).

My TA taught my discussion class that a good way to convert units is to simply substitute the power of 10 associated with the prefix for the prefix when doing calculations. For example, 1 mmol would become 1x10^-3mol.

[Sang Hyoun Hong 3G]

mmol is basically the mol with the prefix milli. In class, we went over how milli, written through the symbol m, is a factor of 10^-3. So 1 mmol= 1 mol x 10^-3

[Fionna Shue 4L]

A mmol is a "millimole", and a "milli-" is a factor of 10^-3. So 1 mmol = 10^-3 mol.

[204765696]

1 mol vs 1 mmol is that 1 mmol is equivalent to 10^-3 mol.

[Anmol_cheema_2F]

The prefix "milli" represents a factor of 10^-3, so a mmol Is 10^-3 mol.

[Arlene Linares 3A]

1mmol is equal to 1x10^-3 mol. the m in front mmol means milli or 10x^-3.

Thank you

An easy way to remember conversions is The Great King Henry Died By Drinking Chocolate Milk. Tera, Giga, Kilo, Hecto, Deca, Base, Deci, Centi, Milli. You can see that because milli is three away from the base to the right, a mmol is 10^-3 mol.
