Pretty basic chem/density problem: finding density of irregular shaped soluble solid

  1. Mar 9, 2008 #1
    well trying to help my little brother with some chem homework, and i believe i am just thinking too hard about this question

    anyways its a whole chem lab thingy about the composition of pennies and one of the thinking questions is

    now when it says "identity" im assuming they are talking about density. mass/volume

    so obviously we weigh the solid to get the mass

    but if it dissolves in water, how are we supposed to get the volume?

    is it as simple as putting the solid in a liquid that it will not dissolve in?

    Yeah, it sounds as simple as putting it in a liquid it won't dissolve in to measure its volume.
