What is the molarity of concentrated acetic acid?

Question

I am trying to make a 1M solution, but this bottle of the concentrated stuff doesn't say what I'm starting with. I guess you're just supposed to know?

All the bottle from the manufacturer says is "Acetic acid, Glacial."

Answer 1

The molarity of anything is the number of moles in 1 dm3.

So for acetic acid density = 1.05 g/ml and the molecular weight is 60 g/mol. So in 1000 ml there are 17.5 moles so the molarity of glacial acetic acid is 17.5M.

Answer 2

Glacial acetic acid is pure, water free acetic acid.

Answer 3

The formula weight of acetic acid CH3COOH (C2H4O2) is 60 grams per mole. Since it is pure, in order to make a 1 Molar solution, combine 1 mole of acetic acid with 1 liter of water. (The formula for Molarity is moles of solute divided by liters of solution so 1 mole/1 Liter = 1 M)
