Homework Help: Chem. Lab

  1. Aug 31, 2006 #1
    Doing a lab on the computer we received the data of a hydrate to be .1989 g and the dehydrate .1271 g last mass of water evolved from reaction .0718g. We heated CuSO4*nH20 and we needed to find n. I changed the anhydrate and water to moles then dividing the number by the smallest amount of moles getting n to be 5 by dividing .000796 mol./.00398 mol. The name of the chemical formula ends up being Copper(II) Sulfate Pentahydrate. Overall we assume 100% yield. Did I do this problem right?
