How many total moles of ions are released when each of the following samples dissolves completely in water? ?
3.70g of CuSO4 5H2O
CuSO4.5H2O ==> Cu^+2 + SO4^- + 5H2O
Convert 3.70 g CuSO4.5H2O to mols CuSO4.5H2O. Then for each mol of the starting material, you obtain 1 mol Cu^+2 ions and 1 mol SO4^-2 ions. Add those together to find the total mols. I've not added the H2O since that doesn't ionize (at least not that much).
