How many milliliter is 80mg?

Answer 1

ml is a size for an amount of fluid.

mg is a size for a mass.

You can convert ml in mg if you know the material your dealing with.

Then you need the periodic system of elements and calculate the molecular weight of you material knowing; mol(n) = mass(mg) / molecular weight(g)

then calculate the volume (ml) =mol(n) / concentration(c)
