Evening

Is g/mol the same thing as mg/mmol? I think so, but I just want to make sure!

Try converting from one unit to the other. That way, you'll always know, no matter what problem you have.  And you'll probably be expected to show your work on an examination.

That all depends on how reasonable we're all willing to be.  I just want my friends back, except for Cartman, you can keep him.

How do you write the m = milli in mathematic form. If you know that you will see the solution easily.

m simply means divide by 1000. So I am dividing by a thousand both numerator and denominator so yes, g/mol is the same thing as mg/mmol!

m simply means divide by 1000.

Depending on how you look at it it either means multiplying or dividing. To convert 0.023 moles to mmol you multiply by 1000 (mmol/mol) and you get 23 mmol.
