What is meant by 0.2mol (12g) of glacial acetic acid how can we make ?
It means weigh out 12g glacial acaetic acetic acid.
The density of glacial acetic acid is about 1.05g/mL and the stuff is about 99.5% pure so if you pipet 11.4 mL that will weigh 12g. However, I don't think you will find a pipet with the volume 11.4 mL. If the 12 g doesn't need to be that accurate you can measure it with a graduated cylinder.
