Is it possible to work out the volume, if you know the density and the molar mass rather than the actual mass of a substance that will be dissolved in a solution? if it makes it any easier, im trying to work out what volume of ethanoic anhydride to use to synthesise apsirin, but i don't know the concentration or mass of solid that will be dissolved in the solution therefore only really know the density and molar mass
Since volume = mass / density, and you have the density..you're missing the mass. However, you got the molar mass and also the number of moles. This makes it possible to find the mass, and hence the volume required.
