How to prepare a 100mg/ml solution of glacial acetic acid in methanol? The density of glacial acetic acid is 1.05 g/cm^3.
The way you do this is to make up more than 1 mL at a time. Instead of weighing out 100 mg and diluting to 1 mL, why don't you try to weigh out ten times that amount and dilute it to 10 mL? Or 100 times that amount and dilute it to 100 mL?Now what happens if the desired concentration is just too small to weigh out...How would you calculate the volume needed arithmetically?
