Mole notation

[Funmi Baruwa]

When we write molar mass do we use the notaion g.mol^-1 or g/mol or are they interchangeable?

[EnricoArambulo3H]

They are interchangeable because mol^-1 is the same as 1/mol, but normally I use g/mol when I'm writing out a problem. Hope this helps!

[Justin Zhang_1A]

They are interchangeable and are both acceptable, so it comes down to personal preference.

[Chem_Mod]

They are the same so either is fine! Whichever you prefer.

[Annette Fishman]

They are interchangeable and are equivalent in value. I personally use g/mol because I think the negative exponent doesn't look as "clean", but it comes down to what you feel most comfortable with.

Hello,
g.mol^-1 is the same as g/mol the ^-1 just means the mol is in the denominator.

[Hannah Rim 2D]

They're interchangeable! Personally, I like to use g/mol because it's easier to work with when doing dimensional analysis. Both are fine though; the negative exponent in mols automatically puts mols on the denominator.

g.mol^-1 and g/mol are interchangeable so you can use whichever you prefer!
