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" I am 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?

Explain how you might determine the identity of an irregularly shaped solid that is soluble in water
