Solid copper(II) chloride forms a hydrate of formula CuCl2 ⋅ xH2O. A student heated a sample of hydrated copper(II) chloride, in order to determine the value of x. The following results were obtained:       mass of crucible = 16.221 g      mass of crucible and hydrated copper(II) chloride = 18.360 g      mass of crucible and anhydrous copper(II) chloride = 17.917 g   At. Mass: Cu 63.55   Cl 35.45   H 1.008    O 16.00  1. Calculate percentage of H2O (answer must have 4 sig. fig)
