–Diluting a solution reduces the number of moles of solute per unit volume, but the total number of moles of solute in solution does not change. •The total number of moles of solute remains unchanged upon dilution, so you can write this equation. •M 1 and V 1 are the molarity and volume of the initial solution, and M 2 and V

The formula for Epsom salts can be written as MgSO4 x H2O, where x indicates the number of moles of water per mole of MgSO4. When 5.061 g of this hydrate is heated to 250 ˚C, all of the water of hydration is lost, leaving 2.472 g of MgSO4.

1 mole of AgCl requires 1 mole of Cl-ion. So, 2 mole of AgCl requires 2 mole of Cl- ion. So, 2 moles of Cl must exist outside the coordination sphere of the coordinate compound, i.e. exist as ion in the compound. Hence the structural formula is [Pd(NH 3) 4]Cl 2 and its IUPAC name is tetraamminepalladium(II) Chloride.
