Q:

What is the molarity of glacial acetic acid?

A:

Quick Answer

The molarity of glacial acetic acid is 17.5M, according to Salt Lake Metals. Since the molarity of any element is determined by the number of moles in 1 dm3, its molarity is calculated by determining its density and molecular weight.

Full Answer

Acetic acid has a density of 1.05 g/ml and a 60 g/mol molecular weight. Therefore, in a 1000ml there exist 17.5 moles. Convertunits.com notes that the formula weight of acetic acid CH3COOH (C2H4O2) is 60 grams in a mole. One molar solution is made by combining one liter of water with one mole of acetic acid.

Thus, we get this formula 1M=1mole/ 1 liter.

Glacial acetic acid is a colorless liquid with a pungent smell. It is soluble in ethanol, water, ethyl ether and glycerol, but insoluble in carbon disulfide. Due to these components, it is used in making acetic anhydride, vinyl acetate, ethyl cellulose and acetic ester.
